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

400kgm/s

Step-by-step 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
