An object slides off a frictionless, horizontal table from a height of 1.40 m above the floor. It strikes the floor a distance of 1.88 m from the base of the table. a) Calculate the speed with which the object leaves the table. b) Calculate the velocity (magnitude and direction) of the object just before it strikes the floor.

A bucket is thrown vertically down a well with a speed of 4.24 m/s, it takes 1.96 s for the bucket to reach the bottom of the well What is the height of the well?

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.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.61 m/s. The stone subsequently falls to the ground, which is 17.3 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. A) Impact speed: _________________________ m/s     B) How much time is the stone in the air? elapsed time: ____________ s
