- I. Conceptual Physics. Justify your answer. 1. A 10-gram rubber ball and a 10-gram clay ball are thrown at a wall with equal initial speeds. The rubber ball bounces, the clay ball sticks. Which ball exerts a larger impulse on the wall? Justify your answer.Asteroid X, speeding at 100 m/s towards an equally massive but stationary asteroid Y, collides with a glancing blow. After collision, X is deflected 350 from its original direction while Y travels at 450 to the original direction of X. See the before & after picture of the collision below. Assuming total momentum is conserved, find the speed of each asteroid after collision. a.) V = 58.2 m/s, v = 71.8 m/s b.) v = 58.2 m/s, V = 71.8 m/sD-E thank you!
