A male and a female trampolinist are at the same height, which is halfway to theirmaximum height. One is going up whilst the other is coming down. At this halfwayheight:Their velocities are equal to their accelerations.Their velocities and accelerations are both equal and opposite.Their accelerations are equal but their velocities are equal and opposite.Their velocities are equal but their accelerations are equal and opposite.Their velocities and accelerations are proportional to their masses.Their velocities and accelerations are equal.Previous PageNext PagePage 14 of 14

A car starts from rest, then accelerates at a constant rate over a distance of 72 m. It then immediately decelerates at a constant rate over a distance of 141 m. The entire trip lasts a total duration of 13.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?
In order to pass a physical education class at a university, a student must run 1.0 mi in 13.3 min. After running for 10 min, she still has 670 yd to go. If her maximum acceleration is 0.15 m/s?, can she make it? (Assume the student runs at a constant speed for the first 10.0 min.) O Yes O No If the answer is no, determine what acceleration she would need to be successful. (If the answer is yes, enter 0.) |m/s²
Consider two cars, a 700kg Porsche and a 600kg Honda Civic. The Porsche is speeding along at 40 m/s (mph) and the Civic is going half the speed at 20 m/s. If the two cars brake to a stop with the same constant acceleration, are either the amount of time required to come to a stop, or the distance traveled prior to stopping influenced by their initial velocity?
