A bat strikes a 0.145 kilogram baseball. Just before impact, the ball is traveling horizontally to the right at 44.0 m/s, and it leaves the bat traveling to the left at an angle of 30 degree above horizontal with a speed of 59.3 m/s. If the bat and ball are in contact for 1.80 milliseconds, obtain the vertical and horizontal components of the average force on ball. (Assume that upward and to the right are positive directions) N (horizontal component)
N (vertical component)
Apply two forces to a ring by hanging a mass of 100g at 30 degrees and a mass of 200g at 150 degrees. Find the third force and angle needed to keep the ring in static equilibrium at the center of the table.
