Question 4 Two children start at one end of a street, the origin, run to the other end, then head back. On the way back Joan is ahead of Mike. Which statement is correct about the distances run and the displacements from the origin? A) Joan has run a greater distance and her displacement is greater than Mike's. Mike has run a greater distance and his displacement is greater than Joan's. Joan has run a greater distance, but her displacement is less than Mike's. Mike has run a greater distance, but his displacement is less than Joan's. E) Mike has run a shorter distance, and his displacement is less than Joan's.

Please help! Required information: A cheetah can accelerate from rest to 52.9 m/s in 2.00 s. Assume that the acceleration is constant over the time interval. a) What is the magnitude of the acceleration of the cheetah? b) What is the distance traveled by the cheetah in these 2.00 s? c) A runner can accelerate from rest to 7.30 m/s in the same time, 2.00 s. What is the magnitude of the acceleration of the runner? d) A runner can accelerate from rest to 7.30 m/s in the same time, 2.00 s. By what factor is the cheetah’s average acceleration magnitude greater than that of the runner?

A skier starts from rest down a slope 500.0 m long. The skier accelerates at a constant rate of 2.00 m/s squared. • a. Find the velocity of the skier at the bottom of the slope. Do this by deriving two separate equations for time and then making the expressions equal to each other to solve for the second velocity. • b. Using the distance down the hill, and the two velocities, determine the time it took to descend the hill.

Can you have a positive or negative velocity but a position with the opposite value (negative or positive)? Explain why or why not. (Explain clear and not too hard to understand) Can you have zero velocity but a positive or negative position? Give an easy example.

Question 8 of 10 View Policies Current Attempt in Progress -/1.25 E ! A race driver has made a pit stop to refuel. After refueling, he starts from rest and leaves the pit area with an acceleration whose magnitude is 6.1 m/s²; after 3.7 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 68.1 m/s overtakes and passes the entering car. The entering car maintains its acceleration. How much time is required for the entering car to catch up with the other car? \t= i eTextbook and Media GO Tutorial Save for Later Last saved 1 second ago.
