- To climb a 400 meter high mountain, you have two options, a straight line route with a 40 ° slope or a route composed of 5 equal sections (same length) each with a 20 ° slope. If traveling in a car with a mass of 1280 kg and a maximum power of 88 kW, Determine (assume the whole car as a particle): a) Is the friction enough to prevent the car from sliding? The coefficient of static friction of the tires with the ground is 0.95. b) What is the power required to climb the 40 ° slope at a constant speed of 40 km / h? Does the car have enough power to go up at that speed? c) What is the constant speed at which the 40 ° slope can be climbed with a 60 kW power? d) What is the power required to climb a 20 ° slope at 40 km/h? Does the car has enough power to go up at that speed? e) In which of the two trajectories does the car do more work?

With the spring initially at equilibrium position, the block was pushed 0.3 meters up the incline by a 50-N external force applied parallel to the path. The coefficient of kinetic friction is 0.30. d) How much work is done by the block (in Joules) on the spring? e) How much work is done by the applied push on the block? f) How much work is done by friction?A large shipping crate is at rest on the horizontal floor of a warehouse. The coefficient of static friction between the crate and the floor is μs = 0.500; the coefficient of kinetic friction is μk = 0.300. Assume that the estimation of the weight of the heaviest crate you could start sliding by pushing on it horizontally is about 100 lb. a) Based on this estimate, what is the magnitude of the maximum force you can apply? b) If you continue to push on the crate with constants force equal to the force calculated in part a) use the impulse-momentum theorem to calculate how long you must push on the crate to give it a speed of 8.0 m/s. Don't forget to take into account the kinetic friction force.

The ramp is inclined at an angle of 40° relative to the horizontal and has a length of 1.50 m.
