A car has a mass of 1850 kg and travels down a 15 degree incline at a constant speed of 100 km/hr. The car rolls on tires that have a radius of 44.95 cm, which roll without slipping. What is the torque being provided by each of the Jeep's brakes? (Assume friction is evenly distributed) and what is the power of each of the breaks?Is mechanical energy conserved?

70kg is sliding up on a hill side at an A mass m incline angle 0 = 30°. The initial velocity of the mass is vi 30m/s, and no external force is applied to the mass on the incline. The height of the structure ish = 25 m Note that the static friction coefficient of snow is i, = 0.5, and kinetic friction coefficient of snow is 0.4. Use the principles of energy and work to find the answen to...

A skier of mass 50.9 kilograms is racing down a hill with an angle of incline of 20.1 degrees. Ignore air resistance and all other types of friction. Yes, I know that is silly. Wait for the next question. What is the acceleration in metres per second squared of the skier?

please calculate the following in details
A quarry truck has a loaded mass of 150 t and is powered by a hydraulic circuit (conceptually, a diesel motor connected to a hydraulic pump are connected to a motor in each wheel hub. Each motor has volumetric and mechanical efficiencies of 0.9 and 0.92, respectively, and the pump has volumetric and mechanical efficiencies of 0.93 and 0.96, respectively. The truck has 2.5 m diameter tyres and 4 motor wheels, with the load...

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 is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53. (a) Find the acceleration of the car. (Take down the ramp to be the positive direction) (b) How long does the car take to skid to a stop if its initial speed is...
