Projection Under uniform Acceleration

Question

A projectile has

Moderate

A

minimum velocity at the point of projection and maximum at the maximum height
B

maximum velocity at the point of projection and minimum velocity at the maximum height
C

same velocity at any point in its path
D

zero velocity at the maximum height irrespective of the velocity of projection

Solution

Motion of a body when projected obliquely can be resolved into horizontal motion and vertical motion.Since acceleration of the projectile is vertically downwards , its vertical component of velocity in upward journey gradually decreases and becomes zero at the highest point and horizontal component of velocity remains unchanged.Therefore , Option -(2) is correct.
