A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.0 m/s, and her takeoff point is 1.1 m above the pool. Which of these two valid methods is the easiest to find how long her feet are in the air? Group of answer choices Break the problem in two parts. For part 1, find the time to reach her highest point by using v0 = 4 m/s, a = -9.8 m/s2, and vf = 0 m/s. For part 2, you can use the highest point above the board found in the previous problem and add it to her height above the pool. Then, using v0 = 0 m/s and a = -9.8 m/s2, you can find the time to reach the ground. Since you only care about the end points in this case, you can use v0 = 4 m/s, a = -9.8 m/s2, and Δy = -1.1 m to find the time to reach the ground.

During your summer internship for an aerospace company, you are asked to design a small research rocket. The rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 980 m above the earth's surface. The rocket's engines give the rocket an upward acceleration so it moves with the acceleration of 16.0 m/s2 during the time T, that they fire. After the engines shut off, the rocket is in free fall. Ignore air resistance. What must be the value of T in order for the rocket to reach the required altitude?
While standing on a sidewalk near his apartment building, Martin throws keys upward to his roommate Thomas. The keys are thrown at 1.7 m height from the ground with the velocity of 15 m/s. Thomas catches the keys when they still move upward with the velocity of 1.4 m/s. At what height from the ground does Thomas catch the keys?
The first astronaut has landed on Mars. Conducting some physics experiments, she drops a hammer from rest from a height of 2.01 m and uses a stopwatch to measure that the hammer takes 1.04 s to hit the ground. A. Determine the magnitude of the acceleration due to gravity on Mars. B. She then throws the hammer straight up into the Martian sky. If she comes back to her hand in 4.20 s, with what speed did she throw it?

The figure below shows a ball thrown from the top of a cliff at a downward angle of θ= 35.9° . It hits the ground a distance D= 7.64 m from the base of the cliff at time t= 1.11 s. What was the initial speed v0 of the ball? Express your answer in m/s to 3 significant figures. Use g=9.81 m/s2.
A stone is thrown vertically upward with a speed of 24.0 m/s. How fast is it moving when it is at a height of 14.0 m? How much time is required to reach this height? Why are there two answers to part B?
A ball is thrown horizontally from the top of a 56.5-m building and lands 122.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.) What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude: _______m/s direction: ______ ° counterclockwise from the +x-axis
A) Compute the position of the sandbag at a time 1.25 s after its release. Express your answer in meters. B) Compute the magnitude of the velocity of the sandbag at a time 1.25 s after its release. Express your answer in meters per second.
A model rocket is fired straight up from the top of a 50-m tall building. The rocket has only enough fuel to burn for 2s. But while the rocket engine is burning fuel, it produces an upward acceleration of 50 m/s^2. After the fuel supply is exhausted, the rocket is in free fall and just misses the edge of a building as it falls back to the ground. Ignoring air resistance, calculate a. the height above the ground and the velocity of the rocket when its fuel runs out. b. the maximum height of the rocket c. the time the rocket is in the air. d. the rocket's velocity the moment before it hits the ground.
Emily challenges her husband, David, to catch a $1 bill as follows. She holds the bill vertically as in Figure P2.69, with the center of the bill between David’s index finger and thumb. David must catch the bill after Emily releases it without moving his hand downward. If his reaction time is 0.2 s, will he succeed? Explain your reasoning. (This challenge is a good trick you might want to try with your friends.)
Dylan and Sophia are walking along Bluebird Lake on a perfectly calm day. Dylan, determined to impress Sophia by his ability to skip rocks, picks up the flattest rock he can find and gives it a sidearm launch from the edge of the water. The rock acquires a completely horizontal speed of 27.2 m/s from a height of 0.54 meters above the water surface. How much time does it take to hit the surface of the water?
A student drives a moped along a straight road as described by the velocity–time graph in Figure P2.58. Sketch this graph in the middle of a sheet of graph paper. (a) Directly above your graph, sketch a graph of the position versus time, aligning the time coordinates of the two graphs. (b) Sketch a graph of the acceleration versus time directly below the velocity–time graph, again aligning the time coordinates. On each graph, show the numerical values of x and ax for all points of inflection. (c) What is the acceleration at t = 6.00 s? (d) Find the position (relative to the starting point) at t = 6.00 s. (e) What is the moped’s final position at t = 9.00 s?
