Which law explains the horse and the cart problem?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. Newton’s second law tells us that acceleration is equal to the net force divided by the mass of the system. …

What force causes the horse to move forward?

The correct answer is (D)The Ground Exerts On Him. When a horse pulls a wagon, the force that causes the horse to move forward is the force that pushes the ground in the backward direction. This is the third law of motion.

When a horse pulls a cart the force that makes the horse run forward is the force exerted by?

ground
The force in turn pulls the cart as the horse moves forward. So, the movement of the horse is due to the force exerted by the ground. This force is known as friction force.

What law of motion is horses pulling a carriage?

third law of motion
A horse is pulling a carriage on a level ground. The horse knows the third law of motion. He tells the carriage that he will exert a force forward, and the carriage will exert a force equal to the horse’s force but in opposite directions.

Can a horse push a cart?

Answer: A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. This force moves the horse and the cart forward.

What is the force of pushing a cart?

The rolling force should be less than 40 pounds. If the force has to be sustained for a minute, or if the cart has to be pushed for more than 10 feet, this should drop to 25 pounds or less. If the exerted force is sustained without a break for four minutes, the acceptable force drops to about 7.5 pounds.

When a wagon is pulled by a horse?

Complete step-by-step solution: When a horse pulls a wagon, the ground is pushed backwards by the horse. The ground exerts a forward force of equal magnitude due to the third law of motion. The waggon moves forward because the backward force applied by the vehicle is less than the force applied by the horse.

What force is used in pulling cart?

The forces on the cart include the forward force the horse exerts on the cart and the backward force due to friction at the ground, acting on the wheels….

When a horse pulls a cart who does the work a cart B Wheels C Road D horse?

(d) When a horse-pulls a cart, work is being done by horse.

Why is a horse able to pull a cart?

Normal reaction and the gravitational force balances each other while the force exerted by the horse on the cart is greater than the frictional force acting on the cart due to the ground. Due to this unbalanced force horse is able to pull the cart.

How does a horse cart move?

A horse pushes the ground in a backward direction. According to Newton’s third law of motion, a reaction force is exerted on the horse in the forward direction. This force moves the horse and the cart forward. As a result, the cart moves forward.

Why do carts move?

The proper definition is: When an object (A) exerts a force on another object (B), the second object also exerts a force on the first object, of equal magnitude and opposite direction. So when the horse exerts a force on the cart, why does the cart move? The cart moves because the horse exerted a force on the cart.

Why does a cart move when you pull it?

That is why when you pull something, you feel it pulling back at you. Calculate the net forces acting on both objects. The cart will move if the horse is able to move, and for the horse to move, the force that it exerts on the cart should be greater than the force the cart exerts on it.

Why do horses and carts move at the same speed?

As the horse exerts greater force, both horse and cart move, accelerating from zero to some velocity. During that acceleration the net forward force on the horse must be greater than the net backward force on the horse. And also, the net forward force on the cart must be greater than the net backward force on the cart.

What is the horse and cart problem in physics?

The Horse and Cart Problem. A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton’s third law the cart must then exert an equal and opposite force on the horse. Newton’s second law tells us that acceleration is equal to the net force divided by the mass of the system.

What is the acceleration of a horse pulling a cart?

A horse is harnessed to a cart. If the horse tries to pull the cart, the horse must exert a force on the cart. By Newton’s third law the cart must then exert an equal and opposite force on the horse. Newton’s second law tells us that acceleration is equal to the net force divided by the mass of the system. ( F = ma, so a = F/m .)
