Answer:
maximum height
or,
initial kinetic energy=E=
when u is the initial velocity and m is the mass of particle.
then the kinetic energy at the highest point,
=E/4

Answer:
velocity at maximum height;Vx=u cosalpha
initial k.e=1/2mu2
k.e at maximum height E1=1/2mVx2=1/2mu2cos2alpha
=1/2 cos(60)^2=E/4
