A car starting from rest on a horizontal road accelerates for 11 seconds until it reaches a speed of 35 m/s. It then maintains this speed until it starts driving up a hill that is a 11° incline. Just as the car starts up the hill the engine dies and it coasts to a stop on the hill.
A) Sketch the car’s trip. You can treat the horizontal and sloped parts as separate but connected. Identify all variables. Collect all known quantities.
B) What is the acceleration the car experienced on the horizontal part of the strip?
C) How far did the car drive to reach 35 m/s on the horizontal road?
D) What is the acceleration of the car on the hill?
E) How far does the car coast on the hill until it stops?

A car accelerates from rest on a horizontal surface. The engine provides a torque of τ = 200 Nm on each of the two front wheels. Each of the four wheels on the car weigh m = 15 kg, have radius R = 35.0 cm and can be considered solid, uniform discs. The rest of the car (not the wheels) has a mass of M = 1000 kg. a) What is the acceleration of the car? I am trying to...

A car of mass 1100 kg starts from rest at sea level and climbs a hill of height 50.0 m. At the top of the hill, the car has a speed of 25.0 m/s, and at this instant, the driver shuts off the engine of the car. The car then coasts down the other side of the hill to height of 15.0 m above sea level. Assume that friction and air resistance are negligibly small. a) (6 pts) How much...

A car drives up a straight incline of 4.8 km in length and .3 km in height. The car moves up the incline at a steady speed of 16 m s^-1, with friction force being 500 N and total weight of car and driver being 12000 N. From the top of the incline, the road continues downwards in a straight line. At the point where the road starts to go downwards, the driver stops the engine and allows the car...

There is a 7.8 × 10^3 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 19.8◦ with horizontal. average frictional force of 4.3×103 N impedes its motion so car’s speed at bottom of driveway is 4.2 m/s. a= 9.81 m/s2 . What is the length of the driveway? Answer in units of m.
