Question

Compare the linear momentum of two bodies one of mass 5 g moving with a speed of 50 ms-1 and another body of mass 0.5 Kg moving with a speed of 0.5 ms-1.

Answer 1

Answer:

Object A is 250gm/s

Object B is 250gm/s

both objects momentum are same.

Explanation:

Momentum=P

Body A

mass= 5g

velocity=50m/s

momentum = mv

=5×50

= 250gm/s

Body B

mass= 0.5g

convert M.K.S TO C.G.S

1KG IS EQUAL TO 1000GRAMS

0.5 KG IS EQUAL TO 0.5×1000

=500GRAMS

SO OBJECT B MASS IS EQUAL TO 500GRAMS

P=MV

=500×0.5

=250gm/s

OBJECT A's momentum is 250gm/s

B's momentum is 250gm/s.

Answer 2

Explanation:

Momentum=P

Body A

mass= 5g

velocity=50m/s

momentum = mv

=5×50

= 250gm/s

Body B

mass= 0.5g

convert M.K.S TO C.G.S

1KG IS EQUAL TO 1000GRAMS

0.5 KG IS EQUAL TO 0.5×1000

=500GRAMS

SO OBJECT B MASS IS EQUAL TO 500GRAMS

P=MV

=500×0.5

=250gm/s

OBJECT A's momentum is 250gm/s

B's momentum is 250gm/s.
