Question

Object X of 10kg and Y of 20 kg are moving with a velocity of 20m/s and 5m/s respectively. Which object will have greater momentum?​

Answer 1

Answer:

object of 10 kg mass

Explanation:

as we know

p=mv

so object Xp=10×20=200kgm per sec

obj Yp=20×5=100kgmper sec

Answer 2

Given:

Object X of 10kg and Y of 20 kg are moving with a velocity of 20m/s and 5m/s respectively.

To find:

Which object has higher momentum?

Calculation:

• Momentum is a vector quantity characterized by the product of mass and velocity vector.

• Momentum = Mass × Velocity

• SI UNIT of momentum is kg m/s.

For Object X:

$P_{X} = 10 \times 20 = 200 \: kg \: m {s}^{ - 1}$

For Object Y:

$P_{Y} = 20 \times 5 = 100 \: kg \: m {s}^{ - 1}$

So, object X has higher momentum that object Y.
