A ball of mass 250 g is thrown with an initial velocity of 25 m/s at an angle of 30 with the horizontal direction. Ignore air resistance. What is the momentum of the ball after 0.2 s? (Do this problem by finding the components of the momentum first, and then constructing the magnitude and direction of the momentum vector from the components.)

You throw a small bouncy ball of mass mjat a hill of mass m, that is sloped at an angle 0 relative to horizontal as indicated in the picture. The ball impacts the hill with an initial velocity vo that is horizontal. During the collision, which lasts from t = 0 until t = t1, the magnitude of the force from the hill on the ball is given by |Fna(t)| = F1sin t1 with F1 a constant. The direction of the force is perpendicular to the hill, as indicated in the picture. The direction of the force from the hill on the ball is perpendicular to the hill. Chosen coordinate System
