Question

What is the mass of an object moving at a speed of 5 m/s and has a momentum of 20 kg . m/s?

Answer 1

Answer:

Explanation:

The equation for momentum is

p

=

m

v

, where

p

is momentum,

m

is mass in kg, and

v

is velocity in m/s.

Momentum for 5 kg, 4 m/s object.

p

=

5 kg

×

4 m/s

=

20

kg

⋅

m/s

Momentum for 20 Kg, 20 m/s object.

p

=

20 kg

×

20 m/s

=

400 kg
