Maximum height reached by the body
H = u² / (2g)
= (9.8 m/s)² / (2 × 9.8 m/s²)
= 4.9 m
P.E at highest point = mgh
= 0.5 kg × 9.8 m/s² × 4.9 m
= 24.01 Joule
At highest point magnitude of velocity of body will be zero.
∴ It’s K.E at highest point is zero.
H = u² / (2g)

= 4.9 m
P.E at highest point = mgh

At highest point magnitude of velocity of body will be zero.
∴ It’s K.E at highest point is zero.
