Acar starts from rest, speeds up with constant acceleration, and travels 350 meters in 5 seconds. what was the average velocity of the car in m/s? 70 m/s omputer's answer now shown above.
what was the final velocity of the car (in m/ m/s submit answer tries 0/2 consider that the car started at rest.
what was the change in velocity of the car (in m/ m/s submit answer tries 0/2
what was the acceleration of the car (in m/s2)? /s2
remember that the acceleration is the change in velocity divided by the change in time

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.
