A 8 kg bowling ball is moving at a speed of 6 km/h, west direction. The momentum of the ball is O a. 13.33 kgm/s, east O b. 48 kgm/s, east O. 13.33 kgm/s, west O d. 48 kgm/s, west

@ULM E My Courses This Course Ha E7.A 75-kg front-seat passenger in a car moving initially with a speed of 23 m/s (50 MPH) is brought to rest by an air bag in a time of 0.3 s. What is the impulse acting on the passenger? E8.A ball traveling with an initial momentum of 1.7 kg-m/s bounces off a wall and comes back in the opposite direction with a momentum of -1.7 kg-m/s. What is the change in momentum of the ball? E9.A ball traveling with an initial momentum of 5.1 kg-m/s bounces off a wall and comes back in the opposite direction with a momentum of -4.3 kg-m/s. What impulse is required to produce this change? E11.An ice skater with a mass of 70 kg pushes off against a second skater with a mass of 30 kg. Both skaters are initially at rest. (a) What is the total momentum of the system after they push off? (b) If the larger skater moves off with a speed of 2.8 m/s, what is the corresponding speed of the smaller skater? E12.A rifle with a mass of 3.4 kg fires a bullet with a mass of 7.8 g…
