At the highest Point, K. E.= 1/2 m(v cos θ)²= mv²/4 = 1000/2 = 500J
No. (highest point of vertical upward motion under gravity)

A projectile is fired with Kinetic energy 1 KJ. If the range is maximum, what is its Kinetic energy, at the highest point ? Ans: here 1/2 mv²=1 KJ = 1000j, θ=45°
At the highest Point, K. E.= 1/2 m(v cos θ)²= mv²/4 = 1000/2 = 500J
At the highest Point, K. E.= 1/2 m(v cos θ)²= mv²/4 = 1000/2 = 500J
