A 72 kg clown is shot from a cannon and reaches a speed of 9.1 m/s. If an average force of 765 N was applied to the clown, how long did it take him to reach the final speed,
assuming he starts from rest? Use impulse and momentum to solve and round your
answer to 2 decimals.

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.
