Given:
let v be initial velocity.
K.E= E =1/2 mV²
VELOCITY OF PARTICLE AT HIGHEST POINT = vcos 45
kinetic energy of particle at highest point is =1/2 m(vcos45)²
=1/2(mv²)(1/2)
=1/2 E



mark me brainest

K.E= E =1/2 mV²

VELOCITY OF PARTICLE AT HIGHEST POINT = vcos 45

kinetic energy of particle at highest point is =1/2 m(vcos45)²

=1/2(mv²)(1/2)

=1/2 E
