- Which of the following best describes how to calculate the average acceleration of any object? Average acceleration is always halfway between the initial acceleration of an object and its final acceleration. Average acceleration is always equal to the change in velocity of an object divided by the time interval. Average acceleration is always equal to the displacement of an object divided by the time interval. Average acceleration is always equal to the change in speed of an object divided by the time interval.arrow_forwardThe figure shows the velocity versus time graph for a car driving on a straight road. Which of the following best describes the acceleration of the car? v (m/s) t(s) The acceleration of the car is negative and decreasing. The acceleration of the car is constant. The acceleration of the car is positive and increasing. The acceleration of the car is positive and decreasing.

A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land?
