Suppose the time between the apparatus leaving your hand and landing on the ground was measured to be t = 4.80 s. What was the velocity of the apparatus leaving your hand?

High-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on the graph to answer the questions. Figure alg 150 100 50 0 0 0.5 1.0 1.5 Part E Use the graph to find the flea's maximum speed.

A car is initially traveling at a rate of 65 feet per second. The acceleration of the car is 3 feet per second squared. Determine the displacement of the car at time t if the displacement at t=5 seconds is 29 feet. Do not include "s(t)=" in your answer.

IXFQP A police car traveling 95.0 km/h is traveling west, chasing a motorist traveling at 80.0 km/h. What is the velocity of the motorist relative to the police car? What is the velocity of the police car relative to the motorist? If they are originally 250 m apart, in what time interval will the police car overtake the motorist?

An unidentified flying object (UFO) is observed to travel a total distance of 42000 m, starting and ending at rest, over a duration of 2.07 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.     39,207 g s     19,604 g s     3,997 g s     1,998 g s

An object was observed to have velocity v1 in m/s at time t1 seconds and later velocity v2 in m/s at time t2 seconds: v1=8; t1=2.4; v2=4; t2=4.0 Units are m/s and s. Find the average acceleration of the object in m/s/s.
