Finally, the water park at an amusement park has rides that are essentially this lab on a large scale. A 45 kg rider falls a total distance of 22.5 m for one of these, sliding down an incline of 31.5 degrees. If there were no friction, how long would the ride last (while they are in the tube?) How fast would they exit the tube in m/s?

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
