A mass m1 is suspended on a string of length L = 1.14 meters. It is pulled back to an angle 9 = 60 degrees with the vertical and released. See gure below. Assume g = 9.8 m/s"2. a) Find the angular velocity of mi about an axis through the suspension point when the mass reaches its lowest point in rad/s. Enter an answer with one decimal place in the box below. (Hint: Use conservation of energy to solve this problem.) '7 Q a) b) You now use the same apparatus to perform a collision experiment where the hanging mass m; = 2.0 kg collides elastically with a second mass m2 (at rest) which it hits when it reaches the bottom of its swing. If the velocity of m1 is v1 = +9.8 m/s before the collision, and its velocity is -3.2 m/s after the collision, what is the size of m2 in kilograms? Enter an answer with one decimal place in the box below. c) What is the velocity of mass m2 after the collision? Show all of your work and your answer in your Crowdmark submission
