- Is it possible for speed to be constant while acceleration is not zero? Give an example of such a situation.arrow_forwardThe driver of a truck slams on the brakes when he sees a tree blocking the road. The truck slows down uniformly with an acceleration of 5.60 m/s2 for 4.20 s. making skid marks 62.4 m long that end at the tree. With what speed does the truck then strike the tree?arrow_forwardThe average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time would be required for the car to accelerate from rest, to 60.0 miles per hour? (The car would need rocket boosters!)arrow_forward
- Consider a grey squirrel falling out of a tree to the ground. (a) If we ignore air resistance in this case (only for the sake of this problem), determine a squirrel's velocity just before hitting the ground, assuming it fell from a height of 3.0 m. (b) If the squirrel stops in a distance of 2.0 cm through bending its limbs, compare its deceleration with that of the airman in the previous problem.arrow_forwardAn airplane flying directly eastward at a constant speed travels 300 km in 2.0 h. (a) What is the average velocity of the plane? (b) What is its instantaneous velocity?arrow_forwardA motorboat starting from rest travels in a straight line on a lake. (a) If the boat achieves a speed of 8.0 m/s in 10 s, what is the boats average acceleration? (b) Then, in 5.0 more seconds, the boats speed is 12 m/s. What is the boats average acceleration for the total time?arrow_forward
- If a car is traveling eastward, can its acceleration be westward? Explain.arrow_forwardWhen the pilot reverses the propeller in a boat moving north, the boat moves with an acceleration directed south. Assume the acceleration of the boat remains constant in magnitude and direction. What happens to the boat? (a) It eventually stops and remains stopped, (b) It eventually stops and then speeds up in the forward direction, (c) It eventually stops and then speeds up in the reverse direction, (d) It never stopsarrow_forwardIf an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible, how would its speed upon return compare with its initial speed? How would the maximum height to which it rises be affected?arrow_forward
- What is the acceleration of a rock thrown straight upward on the way up? At the top of its flight? On the way down?arrow_forwardWhen the pilot reverses the propeller in a boat moving north, the boat moves with an acceleration directed south. Assume the acceleration of the boat remains constant in magnitude and direction. What happens to the boat? (a) It eventually stops and remains stopped. (b) It eventually stops and then speeds up in the forward direction. (c) It eventually stops and then speeds up in the reverse direction. (d) It never stops but loses speed more and more slowly forever. (e) It never stops but continues to speed up in the forward direction.arrow_forwardAn object is dropped from a height of 75.0 m above ground level. (a) Determine the distance traveled during the first second. (b) Determine the final velocity at which the object hits the ground. (c) Determine the distance traveled during the last second of motion before hitting the ground.arrow_forward
