2 points

37.5 kg

375 kg

3.75 kg

0.375 kg

​

Answer 1

Given:-

• Velocity of the body , v = 20m/s

• Linear momentum , p = 7.5kgm/s

To Find:-

• Mass of the body ,m

Solution:-

As we know that Linear momentum is the product of mass and velocity.

• p = mv

Substitute the value we get

→ 7.5 = m × 20

→ m = 7.5/20

→ m = 0.375 kg

∴ The mass of the body is 0.375 Kg

Hence, Last option is the correct answer.
