A body is projected vertically upwards at a speed of 63m/s. if g = 9.8m/ s². Find the maximum height reached?
It reaches maximum height, H, when the initial kinetic energy (1/2)MVo^2 equals the potential enmergy gain mgH.
At that time,
H = Vo^2/(2g)
A projectile of mass 40g is fired vertically and reached a maximum height of 40m.calculate the potential energy at highest point(g=10m/s-2)
