A ball of mass 2 kg is thrown from a tall building with velocity

→

v

= (20 m/s)

^

i

+ (24 m/s)

^

j

at time t = 0 s. Change in the potential energy of the ball after t = 8 s is
(The ball is assumed to be in air during its motion between 0 s and 8 s,

^

i

is along the horizontal and

^

j

is along the vertical direction, let g = 10 m/s2)
