Question

A ball whose kinetic energy is E, is projected at an angle of 45° to the horizontal. The kinetic energy of the ball at the highest point of its flight will be

(a) E

(b) E/√2

(c) E/2

(d) Zero

Answer 1

Correct option (c) E/2
Explanation :

At the highest point of its flight, vertical component of velocity is zero and only horizontal component is left which is
