A stuntman drives a car of mass 1125 east with a speed of 20m/s.

a. If the car accelerates at a rate of -2m/s^2, how long will it take the car to go 50m

b. The stuntman drives the car off an 80m cliff while going 15m/s. How long will it take the car to land?

c. How far horizontally from the cliff will the car land?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

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

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
