* While babysitting their younger brother, Chrisso and Devin are playing with toys. They notice that the squishy Piglet slows down in a repeatable way when they push it along the smooth wooden floor. They propose a hypothesis that the toy slows down with a constant acceleration, which does not depend on the toy’s initial veloctiy. Foe each of five different initial speeds, they measure the distance traveled by the toy from the time they stop pushing it to the time the toy stops moving, and they measure the corresponding time interval. Their data are presented below. Do the data support their hypothesis? Explain. If yes, determine the average acceleration of Piglet and the maximum speed with which Chrisso and Devin push Piglet.

- Scientists have studied two species of sand lizards, the Mojave fringe-toed lizard and the western zebra-tailed lizard, to understand the extent to which the different structure of the two species’ toes is related to their preferred habitats—fine sand for the Mojave lizard and coarse sand for the zebra-tailed lizard. Shown is a somewhat simplified velocity-versus-time graph for the Mojave fringe-toed lizard.a. Estimate the maximum acceleration of the lizard in both m/s2 and g’s.b. Estimate its acceleration at t = 150 ms.c. Estimate how far it travels in the first 50 ms.arrow_forwardThe figure shows the acceleration-versus-time graph of a particle moving along the x-axis.

- A student performs a simple experiment to find the average acceleration of a falling object. He drops a baseball from a building and uses a string and meter stick to measure the height the ball was dropped. He uses a stopwatch to find an average time of fall for 3 trials from the same height and reports the following data: h =5.25 ± 0.15 m, t = 1.14 ± 0.06 S. a) Use the equation a = 2h/t2 to determine the average acceleration and its uncertainty. b) Comment on the accuracy of the acceleration result. Do you think the student made any mistakes? c) What one suggestion would you tell this student to improve the experimental result?
