A 1150 kg car drives up a hill that is 15.7 m high. During the drive, two nonconservative forces do work on the car: (i) the force of friction, and (ii) the force generated by the car's engine. The work done by friction is −2.91×105 J ; the work done by the engine is 6.74×105 J . Find the change in the car's kinetic energy from the bottom of the hill to the top of the hill.

A 975-kg car (including the driver) crosses the rounded top of a hill of radius 88 m at a speed of 12 m.s-1. Calculate: (i) the normal force exerted on the car by the road (ii) the normal force exerted by the car on the 72-kg driver (iii) the sped of the car at which the normal force on the driver is zero.

Part A If a car has a linear acceleration of 1.8 m/s^2 and the radius of its wheels is 0.33 m, what is the angular acceleration of the wheels? a. 0.18 rad/s 2 b. 0.59 rad/s 2 c. 5.5 rad/s 2 d. 9.8 rad/s 2 Part B Given the angular acceleration in the previous problem, how many revolutions does one of the car’s wheels complete in 10.0 s? Assume the car is initially at rest.

46. A police officer in hot pursuit drives her car through a circular turn of radius 300 m with a constant speed of 80.0 km/h. Her mass is 55.0 kg.What are (a) the magnitude and (b) the angle (relative to vertical) of the net force of the officer on the car seat? (Hint: Consider both horizontal and vertical forces.) I don't understand why the net force in the problem is centripetal force and gravitation. I think there should be normal...

A car drives straight off the edge of a cliff that is h =52 m high. The police at the scene of the accident note that the point of impact is d =88 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as postitive y-direction. Keep 2 decimal places in all answers (a) In this...

6. A motor car, of a total mass 1400 kg, running in top gear at 55 km/h, passes on to a rsing gradient of 1 in 20 at that speed. The road and other resistances may be taken as constant at 270 N/t. With condition unchanged, the speed falls uniformly to 40 km/h in a distance of 360 m. An intermediate gear is then engaged for which the speed ratio between the engine and the road wheels is 9:1 and...

A man on a road trip drives a car at different constant speeds over several legs of the trip. He drives for 50.0 min at 55.0 km/h, 15.0 min at 65.0 km/h, and 45.0 min at 45.0 km/h and spends 20.0 min eating lunch and buying gas. (a) What is the total distance traveled over the entire trip (in km)? (b) What is the average speed for the entire trip (in km/h)?
