1. Calculate the impulse in each example below. a. A 2.0 kg clay ball is accelerated from rest to +15 m/s. b. A 2.0 kg clay ball traveling straight down at -15 m's hits the floor and sticks to it. c. A 2.0 kg superball traveling straight down at -15 m/s hits the floor, then bounces back up at +15 m/s. d. A 1200 kg car slows down from 35 m/s to 25 m/s 2. A 1800 ke car traveling due east at 50 m/s slows to a stop in 15.0 seconds. a. What impulse acts on the car during this event? b. What is the direction of the impulse? c. What is the magnitude of the stopping force
