Question

Is the speed of a projectile zero at the highest point of its trajectory whwn thrown at some angle with horizontal

Answer 1

Answer:

The velocity will be zero at the highest point of trajectory of a projectile because due to gravity any object come down and after reaching maximum height, the object stop for a certain time and then come back to the ground.

Answer 2

Answer:

The velocity will be zero at the highest point of trajectory of a projectile .

Explanation:

Because due to gravity any object come down and after reaching maximum height, the object stop for a certain time and then come back to the ground.

A projectile have a minimum speed at the highest point of its trajectory. This is because horizontal speed of the projectile remains constant. Since the only force exerted on the projectile is gravity, which is 9.8 ms² acting downwards and has no effects on the horizontal velocity.
