A football player, starting from rest at the line of scrimmage, accelerates along a straight line for a time of 3.39 s. Then, during a negligible amount of time, he changes the magnitude of his acceleration to a value of 1.79 m/s². With this acceleration, he continues in the same direction for another 2.58 s. until he reaches a speed of 7.56 m/s. What is the value of his acceleration (assumed to be constant) during the initial 3.39-speriod? Number Units

Ajetliner, traveling northward, is landing with a speed of 68.2 m/s. Once the jet touches down, it has 750 m of runway in which to reduce its speed to 7.16 m/s. Compute the average acceleration (magnitude and direction) of the plane during landing (take the direction of the plane's motion as positive). Number i Units 4
A car starts from rest at t = 0 s, and speeds up with a constant acceleration of 1.66 m/s2 for 6.00 s. Then it continues with a uniform speed for another 6.00 s.

An unidentified flying object (UFO) is observed to travel a total distance of 19000 m, starting and ending at rest, over a duration of 4.23 s. Assuming the UFO accelerated at a constant rate to the midpoint of its journey and then decelerated at a constant rate the rest of the way, what was the magnitude of its acceleration? Express your answer in g s , where 1 g = 9.81 m/s^2.

The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 2.20 m above the floor. The ball hits the floor 0.335 s after your drop it.

What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 39.2 m/s^2 19.6 m/s^2 29.4 m/s^2 62.7 m/s^2
A runner and a cyclist compete in a race over a straight course 20 km long. The runner runs at a steady speed of 10 m/s toward the finish line. The cyclist zips at a speed of 23 m/s toward the finish line for 12 km but upon seeing that he is already far ahead of the runner, he decides to stop and wait for the runner to catch up to him. The runner eventually reaches the cyclist and continues moving toward the finish line. The cyclist waits for a while after the runner passes and then cycles toward the finish line again at 23m/s. Both the cyclist and the runner cross the finish line in the exact same instant. Assume both of them, when moving, move steadily at their respective speeds. (a) How far is the runner from the finish line when the cyclist resumes the race? (b) For how long in time was the cyclist stationery?
The displacement of a particle is given by s = 2t³ - 42t² + 120t - 68 where s is in feet and t is in seconds. Plot the displacement, velocity, and acceleration as functions of time for the first 16 seconds of motion. After you have made the plots, answer the questions. Questions: At t = 3.3 sec, S= i ft, v = i ft/sec, a = i ft/sec At t = 8.9 sec, S = ft, v = i ft/sec, a = i ft/sec Att = 14.2 sec, S= i ft, v = i ft/sec, a = i ft/sec The velocity is zero when t = i i sec and when t = i sec
