If an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible how would its speed upon return compare with its initial speed? why ? Explain. How would the maximum height to which it rises be affected? why? Explain.

Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below (select all answers that are true) Group of answer choices: None of the above choices are correct. they will both have the same speed. the speed of Alice is larger than that of Tom. Alice reaches the surface of the lake first. They reach the surface of the lake at the same time. Tom reaches the surface of the lake first. the speed of Tom is larger than that of Alice.
Fast Car: On a hot day in the flats, the temperature is 103.6 degrees. A driver finds an empty, flat stretch of desert that is 1776 meters long and decides to push the limits of his car.
