A 1000 kg car is parked on a slope that is 30 degrees from horizontal. Calculate all of the forces on the car. B Tension T, Tension T Consider the situation in the diagram. Block A has mass 2kg and block B has mass 1kg. The surface is frictionless. The blocks are accelerating at 1m/s2. What are T and T2?
A car of mass 1000 kg is driving up a 30° slope at constant speed. Draw the free body diagram for the car (accurately!) and label the magnitude of each of the forces. The correct answer is: Friction = 4900 N Weight = 9800 N Normal force = 8487 N How to get it??
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 24-kg skier slides down a slope angled at 20 degrees relative to horizontal, with a constant speed of 8.0 m/s. a) Draw and label a free body diagram for the skier. b) Find the magnitudes of all forces in your diagram
A car with a mass 1,000kg is parked on a hill with a slope of 7.0°. The parking brake is released and the car starts to roll down the hill. A) Assuming that friction is negligible, what will be the force that moves the car down the hill. B) What will be the speed of the car after 50 seconds?
A. Imagine a car (1000 kg), that feels horizontal forces: a drag force, a forward-pointing rolling friction force (frF)on two of its tires, and a backward-pointing rolling friction force (fre) on its other two tires. The car is speeding up. The car is moving to the left. Therefore, I choose to make left the positive direction. Here is a free-body diagram (not quite complete) that shows all the forces acting on the car. To be a complete free-body diagram, there...
A car is parked on a cliff that slopes downward by 18.7° below the horizontal. The brakes give out and the car rolls from rest down the cliff. It leaves the edge of the cliff at 21 m/s. The edge of the cliff is 15 m above the ocean. What is the car’s horizontal position relative to the base of the cliff at the instant the car strikes the water? Take the acceleration of gravity to be 9.8 m/s. Can...
1. A 3000 kg truck travelling at 50 km/hr strikes a stationary 1000 kg car, locking the two vehicles together. A) What is the final velocity of the two vehicles? B) How much of the initial kinetic energy is lost to the collision? 2.What is the gravitational force between two masses of mass 30 lbs and 50 lbs, separated by a distance of 2 meters? 3. Hans Full is pulling on a rope to drag his backpack to school across...
3. A cop sits in a parked car 10 feet from parked car 10 feet from a straight road. As you drive along the road, the cop aims & radar um at your car the distance from your car to the cop feet. The radar gun measures the rate a Tacir gun mensures the rate at which your distance from the cop is changing with respect to time, which is ds/dt. Let be the distance, in feet, of your ca...
A 4500 kg truck is parked on a 7.0 degree slope. How big is the friction force on the truck?
