Homework Statement
A 2800 kg truck traveling north at 35 km/h turns east and accelerates to 55 km/h.
What is the change in the truck's kinetic energy?
What is the magnitude of the change in the linear momentum of the truck?
What is the direction of the change in the linear momentum of the truck?
Homework Equations
I know the change in something is Final minus initial, and i have been using momentum=mass times velocity , Kinetic Energy = half mass times velosity's square, but I'm still not getting the right answer. Any suggestions please? Thank you.
