Question

A man throws a ball weighing v500 g vertically opwards with a speed of 10 m/s then what would be its monetum at the highest point of its flight ?

Answer 1

As we know that velocity at the highest point is zero. 

Momentum = mass x velocity = zero. 

Answer 2

We know that the zero is at the highest velocity,

so

monetum is equal to mass x velocity is equal to the (zero)
