A 1200 kg car accelerates from 13m/s to 17m/s. find the change in momentum of the car?

Given:

Mass,

Change in velocity,

            =  4 m/s

Now,

The change in momentum is:

=

=

=

Thus the above answer is correct.

4800

Explanation:

The change in velocity of the car is 17-13=4m/s. Since the change in momentum is the mass multiplied by the change in velocity, the answer is 4*1200=4800. Hope this helps!

i believe it is b. what was the cause of the big bang

hope this !

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
