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

impulse?
0 24 N"s
0 3.33 Nºs
30 N's
0 -30 N's
0-24 N's

Answer 1

24kgm/s

Step-by-step 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
