Question

An 80.0 N force accelerates a 6.0 kg object from 4.0 m/s to 8.0 m/s. What is the

Answer 1

Answer:

24kgm/s

Explanation:

Given parameters:

Force  = 80N

Mass of object  = 6kg

Initial velocity  = 4m/s

Final velocity = 8m/s

Solution:

Impulse  = ?

Solution:

The impulse on a body is its change in momentum.

    Impulse  = m (v  - u )

m is the mass

v is the final velocity

u is the initial velocity

  Now insert the parameters and solve;

          Impulse  = 6 (8 - 4) = 24kgm/s
