An object acted on by three forces moves with constant velocity. One force acting on the object is in the positive x direction and has a magnitude of 6.5N ; a second force has a magnitude of 4.0N and points in the negative y direction.
a. Find the magnitude of the third force acting on the object.
b. Find the direction of the third force acting on the object.
A 0.570 kg ball is dropped from rest at a point 1.50 m above the floor. The ball rebounds straight upward to a height of 0.800 m. Illustrate what are the magnitude and direction of the impulse of the net force applied to the ball during the collis..
