Question

. An object of mass 2kg travelling along a straight line with a velocity of 8 m/s. Find it's momentum? * a. 16 kg m s b. 4 kg m/s c. 4 kg m s d. 16 kg m/

Answer 1

$\boxed{\bf{\red{\bigstar Answer: }}}$

• Momentum = Mass × velocity
• = 8 ×2
• = 16 kgm/s^2

Answer 2

Given:

Mass of the object = 2 kg

Velocity of the object = 8m/s

To find:

The momentum of the object

Calculation:

We know the formula

Momentum = mass × velocity

=> p = mv

By substituting the given values in the formula

=> p = 2×8

=> p= 16 kg-m/sec

The momentum of the object is 16 kg-m/sec [option(a)]
