1) beth rode the flying saucer ride at her favorite amusement park. the ride hung from a rod and swung back and forth while simultaneously spinning in a circle. what type of motion did beth experience? a) translational motion b) spinning motion c) rotational motion d) translational and rotational motion 2) jill and scott both road their bikes for 30 minutes. jill traveled 5 kilometers and scott traveled 10. calculate each person's speed and tell who rode faster. (s=d/t) a) scott had the faster speed since he rode at 10 km/h and jill was riding at 5 km/h b) scott had the faster speed since he rode at 20 k/h while jill only traveled 10 km/h. c) jill was traveling faster. she was riding at a speed of 10 km/h while scott was traveling at 20 km/h. d) both jill and scott were traveling at the same speed since they both rode their bikes for 30 minutes. 3) james and haley went to the speedway to watch cars race around an oval track. one car traveled at a constant speed for the entire race. james told haley that the car was accelerating during race, but haley said james was wrong since the car traveled at a constant speed. who was right and why? a) haley was right since the car didn't win the race it was not accelerating. b) haley was right because the car traveled at a constant speed. acceleration is a change in velocity. c) james was right since the car changed direction during the race. d) james was right because the car was a race car and all race cars accelerate during a race.
