What is the velocity of the body 25 m above the ground?

25/9.8 = 2.551 s. Maximum height 31.25 metres. Velocity at s = 25 metres is m/s.

When a cricket ball is thrown vertically upwards with a speed of 20 m s?

In your question, the initial velocity is given as 20m/s , i.e., u=20m/s , the final velocity that the ball can achieve at the maximum height is 0m/s , hence, v=0m/s . Since the only first that cause the acceleration is gravity, a is taken as g where g is acceleration due to gravity, and had a value of 9.81m/s2 .

When a ball is thrown vertically upwards from the ground?

It crosses a point at the height of 25 m twice at an interval of 4 secs. The ball was thrown with the velocity of. ⇒u=30m/s.

What is the speed of the ball at its maximum height?

0 m/s.
At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero.

What is the final velocity of a body thrown vertically upward?

The final velocity is 0 m/s because, at its highest point, the body will stop completely, before falling back to earth. Its acceleration will be negative since, in the direction of travel of the body, gravity is acting as a decelerating force. A body thrown vertically upward with a speed of 25 m/s.

What is the initial velocity of the ball at maximum height?

– Physics Q&A A ball is thrown vertically upwards with a velocity of 49 m/s. Calculate (1) The maximum height to which it rises. (2) The total time it takes to return to the surface of the earth. Initial velocity of the ball (u) = 49m/s. The velocity of the ball at maximum height (v) = 0.

What is the initial velocity of a body at 25m/s?

For a body fired vertically at an initial speed of 25m/s, we know three things;- The body’s initial velocity, u = 25 m/s. Its final velocity, v = 0 m/s. Its acceleration, a = -9.8m/s 2. The final velocity is 0 m/s because, at its highest point, the body will stop completely, before falling back to earth.

Can a human throw a ball at the same height?

Yes, if there is no external resistance. For example, no atmosphere or no birds below 14 meters from ground (the ball thrown should reach 14m). The body will take the same time to go up, as it will take to reach down (from the same height), under the same acceleration.
