Question

calculate the momuntem of a toy car of mass 200g moving with a speed of 5m/s

Answer 1

Answer:

Explanation:

We know what P = m.v ......(1)

Given, m = 200g = 0.2kg

v = 5 m/s

Put these values in (1)

We get, P = 0.2 × 5 = 1 kg m/s

Answer 2

Answer:

1 kg-m/s

Explanation:

mass of car ,m= 200 g

velocity of car , v=5 m/s

1 kg=1000 g

thus , mass of car ; m=0.2 kg

momentum of car , p = mass . velocity

=0.2 . 5

= 1 kg-m/s
