Question

An object of mass 50 kg accelerates from a velocity of 2.0m/s to a velocity of 10 m/s in the same
direction.
What is the impulse provided to cause this acceleration?​

Answer 1

Answer:

400kgm/s

Explanation:

Given parameters:

Mass of object  = 50kg

Initial velocity  = 2m/s

Final velocity  = 10m/s

Unknown:

Impulse provided to cause this acceleration  = ?

Solution:

The impulse is the change in momentum.

  Impulse  = mass x (Final velocity  - Initial velocity )

  Impulse  = 50 (10 - 2)  = 400kgm/s
