A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal.
A ball with an initial velocity of 11.5 m/s and mass 1.9 kg moves at an angle 65.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 65.5° above the horizontal, moving in the opposite direction with the same speed. See the figure.
What was the magnitude of the impulse delivered by the wall, in kilogram meters per second?

A ball of mass m moving with velocity v_i_vec strikes a vertical
wall. The angle between the ball's initial velocity vector and the
wall is theta_i as shown on the diagram, which depicts the
situation as seen from above. The duration of the collision between
the ball and the wall is Deltat, and this collision is completely
elastic. Friction is negligible, so the ball does not start
spinning. In this idealized collision, the force exerted on the
ball by the...
