A 1500 kg car begins Wing down a 5.0 inclined road with a speed of 30...
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:...
4. A car with a mass of 1500 kg moves along a level road with an initial speed of 20 m/s. If the puts on his brakes and slides to a stop with a friction force of 3000N, How far will it take him to stop? Sketch a diagram of the situation.
Show units, check the ones I did and show workj for all parts 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 of mass 1000 Kg descends a hill inclined with horizontal by 30°, the car is traveling at 80 km/h is uniformly brought to rest over a distance of 40 m. Calculate using work-energy method the average braking force required. The resistance to the motion is 200 N. 40 0 = 30°
A 1500 kg car is traveling on a flat surface at 100 km/h. Find the kinetic energy. Assuming no frictional losses so that kinetic energy is transformed to potential energy, if the car then coasts up a hill, how high will it go vertically before it comes to rest?
A 1500-kg car starts from rest and accelerates uniformly to 18.0 m/s in 12.0 s over a dry concrete road. Assume that kinetic friction remains constant at 400 N during this time. – (a) Find the net work done on the car and the work done by the engine. – (b) How many revolutions does each tire make over the 12.0 s interval? What is the angular speed of the wheels when the car has traveled half the total distance?...
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...
A 1200 kg car is coasting on a horizontal road with a speed of 18 m/s . After passing over an unpaved, sandy stretch 35.0 m long, car's speed has decreased to 12 m/s . Part A Was the net work done on the car positive, negative, or zero? Part B Find the magnitude of the average net force on the car in the sandy section of the road. Express your answer to two significant figures and include the appropriate...
