Name Rec. Inst. Hand-in-HW # A 1500 kg car coasting on a horizontal road hits a 500 kg moose. The moose is thrown through the windshield into the passenger compartment. What percent of the initial kinetic energy is lost (turned into non-mechanical forms of energy) in the collision? For thought: why does the initial speed of the car not matter but the fact that it is coasting does? I need the graph of the question and unit check Rep: ID:...

A 1.535-kg car is moving down a road with a slope (grade) of 10% at a constant speed of 13 nVs. What is the direction and magnitude of the frictional force? (define positive in the forward direction, i.e.. down the slope)? A 1.576-kg car is moving down a road with a slope (grade) of 11% while slowing down at a rate of 3.6 rrv'sA2. What is the...

A 1300-kg car, initially at rest, is initially accelerated at 4.9m/s2. After the car moves 550m, the engine is cut off. The car then moves a distance of 1230 before coming to a stop. Assume the road to be level and that g = 10 N/kg. a) What is in m/s, the magnitude of the velocity of the car at the end of the first 550m? b) What is in m/s2, the magnitude of the acceleration of the car while...

a 2.0 kg mass moves along a frictionless horizontal surface at a speed of 5.0 m/s. The mass encounters a 30 degree inclined surface with a constant friction force of 1.5 N. At 1 m high (vertical) the surface levels off and is again frictionless. the mass then encounters a spring with k=10 N/m a) how far is the spring compressed after the mass comes to rest? b) how far down the inclined plane will the mass move after bouncing...

A car drives down a curving road at a constant speed. Which of the following statements are true? (Select all that apply.) A. There is no net force acting on the car as it drives down the road. B. The car is traveling at a constant velocity down the road. C. The car is experiencing no acceleration as it drives down the road. D. The car is experiencing a non-zero net force while driving down the road/ E. The car is experiencing...

A 1030 kg car is pulling a 290 kg trailer. Together the car and trailer move forward with an acceleration of 2.13 m/s2. Ignore any frictional force of air drag on the car and all frictional forces on the trailer. (a) Determine the net force on the car. Magnitude: Direction: Forward/Backward b.)Determine the net force on the trailer: Magnitude Direction: Forward/Backward c.) Determine the force exerted by the trailer on the car. Magnitude: Direction: Forward/Backward d.) Determine the resultant force...
