Question

a man throws a ball of mass 0.5kg vertically upwards with a velocity of 10m/s. what will be its initial momentum what would be its momentum at its highest point of its rate

Answer 1

• Mass=0.5kg
• Velocity=10m/s

`\\ \bull\sf\dashrightarrow Momentum=Mass* Velocity`

`\\ \bull\sf\dashrightarrow Momentum=0.5(10)`

`\\ \bull\sf\dashrightarrow Momentum=5kgm/s`

Answer 2

solution given;

mass(m)=0.5kg

initial velocity (u)=10m/s

now

Initial momentum =mu=0.5Kg×10m/s=5Kgm/s

again:

At highest point its velocity becomes zero so momentum will be zero

as momentum p=mass×velocity.
