A ball is thrown with an initial speed of 20m/s at an angle of 60 to the ground. If air resistance is negligible, what is the ball ‘s speed at the instant it reaches its maximum height from the ground.

Respuesta :

Answer:

when a ball is thrown to the air and it attains it maximum height it's value is 0.

Explanation:

Therefore

V = Ucos angle

V = 20 cos 60°

V = 20 x0. 5

V= 10m/s

The ball‘s speed at the instant it reaches its maximum height from the ground is zero.

The given parameters;

initial speed of the ball, u = 20 m/s

angle of projection, = 60

The velocity of an object thrown upwards reduces as the object ascends upwards. This velocity eventually becomes zero when the object reaches the maximum height. This velocity also increases as the object moves downwards and eventually becomes maximum before the object hits the ground

Thus, the ball‘s speed at the instant it reaches its maximum height from the ground is zero.
