A crazy road near your home, called “Dead Man’s Grade”, involves a 100 m long slope followed by a 20 m drop. The road has long been closed due to many accidents. You and your friends like to push your 25 kg go-cart up the backside of the grade and coast down the steep slope. a. How much force is needed to push the go-cart up the hill?
b. What speed will the go-cart reach at the bottom of the hill? Neglect regarding forces.

An object thrown vertically upward from the surface of a celestial body at a velocity of 36 m/s reaches a height of sequalsminus0.9tsquaredplus36t meters in t seconds. a. determine the velocity v of the object after t seconds. b. when does the object reach its highest point? c. what is the height of the object at the highest point? d. when does the object strike the ground? e. with what velocity does the object strike the ground? f. on what intervals is the speed increasing?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?
