A 1290kg car and 4860kg truck undergo a perfectly inelastic collision. Before the collision, the car was traveling southward at 1.80m/s , and the truck westward at 9.25m/s .
Find the velocity of the wreckage immediately after the collision.
Enter the x and y components of the velocity separated by a comma. Assume that the positive x and y axes are directed eastward and northward, respectively.
A 2 kg ball has been thrown vertically upward. If we ignore the air resistance, what are the direction and size of the net force acting on the ball while it is traveling upward?
