Which of the following statements is true? (a) If a car is traveling eastward, its acceleration must be eastward. (b) If a car is slowing down, its acceleration must be negative. (c) A particle with constant acceleration can never stop and stay stopped.
A jet plane beginning its takeoff moves down the runway at a constant acceleration of 4.30 m/s2. If a speed of 73.0 m/s is required for the plane to leave the ground (assume it’s taking off from rest), how long a runway is required? Group of answer choices 620 m 98 m 435 m 560 m
George (who has poor eyesight and has forgotten his glasses) is driving his car down a straight roadway at 21.7 m / s when he suddenly notices a brick wall erected in the middle of the road 87.2 m away from where he is now. After a 1.10 s reaction time, he slams on the brakes, slowing his car down with a constant acceleration of magnitude 4.90 m / s ^2. Calculate George's total stopping distance (to be more precise: calculate what would be George's total stopping distance if the wall were not there). Does he stop in time or does he hit the wall?
as part of a science experiment a giant rubber bladder filled with oil is dropped from a 30th story apartment window in new york. the bladder falls at a constant acceleration of 9.8 m/s2 downward due to gravity. how long will it take for the bladder to reach a downward velocity of 30.5 m/s?
A train, traveling at a constant speed of 22.0 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.40 m/s2. The speed of the train after 6.40 s on the incline is 13.0 m/s How far has the train traveled up the incline after 6.40 s?

A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. Calculate its velocity just before it strikes the floor. Answer in 2 decimal places. Calculate its velocity just after it leaves the floor on its way back up. Answer in 2 decimal places. Calculate its acceleration during contact with the floor if that contact lasts 8.00 × 10−5s.
