Question

a ball whose ke is E is projected at an angle of 45 to the horizontal .what will be kintic energyof a ball at heights point of flight

Answer 1

Hey Blackdeath
your answer is here

velocity of particle at maximum height is
v = ucostheta

and initial velocity is v

at max height kinetic energy is kcos^theta

so ,
K = k× (1/root2)^2

K = k/2

Hope this help you

Thanks
