A fast, measured pitched baseball left the pitcher's hand at a speed of 49.0 m/s. The pitcher was in contact with the ball over a distance of 1.59 m and produced constant acceleration. (a) What acceleration did he give the ball?

Determine the stopping distances for a car with an initial speed of 93 km/h and human reaction time of 3.0 s for the following accelerations. (a) a = -4.0 m/s2 , but has changed from what was graded. m (b) a = -8.0 m/s2 but has changed from what was grade...

In an experiment, a shearwater (a seabird) was taken from its nest, flown 4760 km away, and released. It found its way back to its nest 14.9 days after it was released. If we place the origin at the nest and extend the +x axis to the release point, what w...

A car moving at 62 mi/h can be brought to rest in 4.8 s. Assuming that the deceleration is uniform, how far will the car travel between the time the brakes are applied and the time the car stops?
