Question

Ball is thrown vertically upward with a speed of 120 m/s its speed at midpath

Answer 1

u=120 m/s
g=10m/s
t=6s
v=u+at
v=120+(-10 )multiply by 6
v=120-60
v=60m/s

Answer 2

Explanation:

momentum is the product of mass and velocity of a particular material . And when ball is thrown vertically upwards its velocity at highest point is zero . Therefore momentum P = m× v = m × 0 =0
