Question

A Man throw a ball weight 500g vertically upwards with speed 10m/s what in initial position

Answer 1

Hey !!

Given-
mass = 500g=>500/1000kg
=>0.5kg

speed = 10ms-¹

initial momentum =>?

momentum at highest point =>?

initial momentum =>mass× velocity
=>0.5×10 = 5 kg.m/s-¹

Remember-

the body experience 0(zero) velocity in it's highest point .
so,
v= 0
then,
momentum at the highest point =>
0.5×0 =>0 answer

hope it's help you !!

Answer 2

Given-

mass = 500g=>500/1000kg

=>0.5kg

speed = 10ms-¹

initial momentum =>?

momentum at highest point =>?

initial momentum =>mass× velocity

=>0.5×10 = 5 kg.m/s-¹v                                                 And momentu0m of its heighest flight is zero because V is not given so P=mv and m=0.5*0
