Question

A man throws a ball weight of 500 gram vertically upwards with a speed of 10 metre square (1) what will be its initial momentum

Answer 1

Answer:

Initial momentum = 5 kg m/s²

Explanation:

We know that,

Momentum = Mass × Velocity

Initial momentum = Mass × Initial velocity

$\boxed{p = mu}$

Given that,

Mass = m = 500g = 500 / 1000 = 0.5 kg

Initial velocity = u = 10 m/s

Putting these values in we get,

p = 0.5 × 10

p = 5 kg m/s

Answer 2

Answer:

Initial momentum = 5 kg m/s²

We know that,

Momentum = Mass × Velocity

Initial momentum = Mass × Initial velocity

Given that,

Mass = m = 500g = 500 / 1000 = 0.5 kg

Initial velocity = u = 10 m/s

Putting these values in we get,

p = 0.5 × 10

p = 5 kg m/s
