Answer:

Given :

Momentum of disc = 42 kg m/s

Velocity of disc = 21 m/s

To Find :

Mass of the disc.

Solution :

❖ Momentum is defined as the product of mass and it's velocity..

Mathematically, p = m × v

p denotes momentum

m denotes mass

v denoted velocity

➛ It is a vector quantity having both magnitude as well as direction.

➛ It can be positive, negative or zero.

➛ SI unit : kg m/s or N s

By substituting the given values;

➙ p = m × v

➙ 42 = m × 21

➙ m = 42/21

➙ m = 2 kg

∴ Mass of the object is 2 kg.

Knowledge BoosteR :

As per newton's second law of motion, force is measured as the rate of change of linear momentum.

Formula : F = dp / dt
