Question

a ball of mass 0.5 kg. is
thrown vertically
upward with a velocity of 15m/s
calculate in s kinetic energy and potential
energy after 1second​

Answer 1

Answer:

Given,

Initial velocity, u=15ms

−1

Acceleration, a=−10ms

−2

Apply kinematic equation of motion

v=u+at

v=15−10×2=−5ms

−1

Hence, velocity after 2sec is 5ms

−1

Downward
