Question

A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 25.0

A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 25.0 degree below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 3.97 m/s2 for a distance of 70.0 m to the edge of the cliff, which is 40.0 m above the ocean. Find the car's position relative to the base of the cliff when the car lands in the ocean. Your response differs from the correct answer by more than 10%. Double check your calculations. m Find the length of time the car is in the air. Your response differs from the correct answer by more than 10%. Double check your calculations. s

Explanation / Answer

a)v=sqrt*(2as)=23.6m/s

vx=vcos25=21.4m/s

time of flight=t

40=23.6Sin25t-0.5*9.8*t^2

t=2.02s

distance=vx*t=43.2m
