Question

The momentum of a ball of mass 70 g moving with a velocity of 20 m/s is = kgm/s. ​

Answer 1

Answer:

Momentum = 14kgm/s

Step-by-step explanation:

Given,

Velocity = 20m/s

Mass = 70kg

Since momentum is the product of mass and velocity,

Momentum = Mass ×Velocity

p = m×v

p = 0.7×20

p=  14kgm/s

Hope this helped!

Answer 2

Answer:

1.4kgm/s

Step-by-step explanation:

Momentum = Mass × Velocity

Mass = 70 g = 70/1000kg = 0.07kg

Velocity = 20m/s

Momentum = 0.07 × 20

=1.4 Kgm/s

hope it is helpful to you ☺️
