Question

An 6 kg object accelerating from 17 m/s to 10 m/s. What is the change in momentum of the object?

Answer 1

The change in momentum (in kg*m/s) = 42

Step-by-step explanation:

The change in momentum is equal to

Final Momentum - Initial Momentum

As we know

Momentum is equal to the product of mass and velocity

`M = m * v`

where m is the mass of the body and v is the speed

Thus, change in momentum

`m_2v_2 - m_1v_1`

here m1 = m2 = 6 Kg

Substituting the given values in above equation we get -

`6 * 17 - 6* 10\\6 (17-10) = 6 * 7 = 42` kg m/s
