How much time did each car take to attain the same velocity?

How much time did each car take to attain the same velocity? Answer : From the graph it is clear that both the cars attain the same velocity at the fifth second i.e., 40 m/s. Since the car A started one second before the car B, so it would take one more second than the car B.

At which instant do the two cars have the same velocity?

time graph; there is never an instant in time in which they share the same velocity. The two cars have the same position at seven seconds; yet they never have the same velocity at any instant in time.

How do you find velocity with acceleration and time?

Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h .

What is the car accelerating?

Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr.

What was the acceleration of car?

The acceleration of cars in the United States is stated as a “zero to sixty” time, where vi is zero and vf is 60 miles per hour or 27 meters per second. The average rate of acceleration of all the ordinary cars I found was between 3 and 4 m/s2. You can find the acceleration of any car listed under its performance.

Does the speed of the vehicle remains the same throughout the journey?

Answer: Average speed is measured in metres per second. An object is travelling at a steady or constant speed when its instantaneous speed has the same value throughout its journey. For example, if a car is travelling at a constant speed the reading on the car’s speedometer does not change.

What is the acceleration of an object moving with constant velocity?

If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that’s not to say that there isn’t work done by individual forces on the object, but the sum is 0 ).

When did the two cars have the same velocity?

What is the slope of the line for the red car for the first three seconds? What is the displacement of each individual car after nine seconds (use the area of the velocity-time graph)? Does the red car pass the blue car at three seconds? If not, then when does the red car pass the blue car?

What is an acceleration vs time graph?

An acceleration vs. time graph plots acceleration values on the y-axis, and time values on the x-axis. time graph, the slope at that point (derivative) will always be equal to the acceleration at that time. So, if at some moment your acceleration is positive, then at that moment your velocity will be increasing.

How do you find acceleration with two velocities and distance?

Calculating acceleration involves dividing velocity by time — or in terms of SI units, dividing the meter per second [m/s] by the second [s]. Dividing distance by time twice is the same as dividing distance by the square of time. Thus the SI unit of acceleration is the meter per second squared .
