Need help please, please draw free body diagrams and sketches for better understanding and provide formulas, thanks.

A mass mj is suspended on a string of length L = 0.98 meters. It is pulled back to an angle 6 = 62 degrees with the vertical and released. See figure below. Assume g = 9.81 m/s"2. a) Find the angular velocity (in rad/s) of m; about an axis through the suspension point when the mass reaches its lowest point. Enter a number with one decimal place (no units) in the box below. Submit your written work to Crowdmark. b) You now use the same apparatus to perform a collision experiment where the hanging mass mq = 1.5 kg collides elastically with a second mass m (at rest) which it hits when it reaches the bottom of its swing. If the velocity of m; isv; = +5.2 2 m/s before the collision, and its velocity is -2.2 7 m/s after the collision, what is the size of m, in kilograms? Enter a number with one decimal place (no units) in the box below. Submit your written work to Crowdmark. Q c) What is the velocity of mass m, after the collision?
