Hey, It's been about 2 weeks since I've had a physics class and I just can't seem to put things together again.(adsbygoogle = window.adsbygoogle || []).push({});

I have two problems that seem like they should be easy, and I'm sure they are, but am unsure on how to do them.

A constant force of 6.00N acts on a 3.00-kg object for 10.0 s. What are the changes in the objects momentum and velocity?

I have the equation momentum p = mv. p=(F)(delta t). Could I just do 6.00-N x 10=(3.00-kg)v and solve for v to find the velocity?

The second problem is

The velocity of a 625-kg car is changed from 10.0 m/s to 44.0 m/s in 68.0 s by an external constant force. What is the resulting change in momentum of the car? What is the magnitude of the force?

I tried to do p=(625)(44-10.0) to find the momentum, but that does not seem right to me. What do i do?
