A car traveling at 34 m/s runs out of gas while traveling up a 9.0 slope
A car traveling at 34 m/s runs out of gas while traveling up a 9.0 slope
Part A
How far will it coast before starting to roll back down? Express your answer in meters.
A piano has been pushed to the top of the ramp at the back of a moving van. The workers think it is safe, but as they walk away it begins to roll down the ramp. Neglect the friction between the piano and the ramp.
Part A
If the back of the truck is 1.5 m above the ground and the ramp is inclined a: 28, how much time do the workers have to get to the piano before it reaches the bottom of the ramp? Express your answer in seconds. Submit

a car is traveling along a straight road when the car runs out
of gas. the car has an acceleration a(t)=1.1m/s^2-.02m/s^3*t and
has a velocity of 30.0m/s at t=0.
