Question

1. Calculate the momentum of a 1,500 kg car traveling at 6 m/s.

Answer 1

Answer:

1.$9000kgm/s$

2.$258,000kgm/s$

Explanation:

1.Momentum is given as the product of mass by velocity of an object.

Momentum,$p=mv$

m=1,500kh, v=6m/s

$p=1500*6\\p=9000kgm/s$

2.Momentum,$p=mv$

m=7800kg, v=30m/s

$p_1=7800*30\\p_1=234,000kgm/s$

new mass=7800+800=8600

As mass is increased, so does the resultant velocity as mass is directly proportional to velocity.

$p_2=8600*30\\p_2=258,000kgm/s$
