**28. Multiple-Concept Example 5 reviews many of the concepts that play roles in this problem. An extreme skier, starting from rest, coasts down a mountain slope that makes an angle of 25.0° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.200. She coasts down a distance of 10.4 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.50 m below the edge. How fast is she going just before she lands?

A box is launched up a rough incline with an initial velocity, vo = 6.3 m/s, as in the figure below. The coefficient of kinetic friction between the box and incline is K = 0.05. The angle in the figure is = 39.8 degrees. What speed will the box have when it returns to its initial position at the bottom? With explanation please. VO 0
1. A box is being pulled up a 40° incline by a 7.0 kg block suspended from a frictionless, massless pulley. The box does not start at the very bottom of the incline. The block is suspended 2.0 m above the ground. The coefficient of kinetic friction between the box and the incline is 0.40. The block is released from rest. At the moment the block hits the ground, the box is traveling at 2.0 m/s up the incline. What is the mass of the box?

In the back of the truck is a 200kg box that has a coefficient of static friction of 0.8 and a coefficient of kinetic friction of 0.4 between the truck and the box. You are driving on the freeway at 25m/s. There is a car ahead of you that is driving at 30m/s. Your front bumper is 30m behind the back of the first car. You would like to pass the other car and pull back into the same lane when your back bumper is 10m ahead of the front bumper of the first car in 5 seconds. The length of the car ahead of you is 3m and the length of your car is 4m.a) What minimum acceleration do you need to do this?b) What distance does your car travel in that time?c) Does the box in your truck start to slide off the truck?
Current Attempt in Progress The figure shows a cold package of hot dogs sliding rightward across a frictionless floor through a distance d = 22.0 cm while three forces act on the package. Two of them are horizontal and have the magnitudes F₁ = 8.0 N and F₂ = 2.0 N; the third is angled down by = 60.0° and has the magnitude F3 = 7.0 N. (a) For the 22.0 cm displacement, what is the net work done on the package by the three applied forces, the gravitational force on the package, and the normal force on the package? (b) If the package has a mass of 4.0 kg and an initial kinetic energy of 0, what is its speed (in m/s) at the end of the displacement? (a) Number i (b) Number Units Units Hot Dogs Ve F F d
Starting from rest, a 30.6 kg child rides a 8.50 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.4 m/s. If the slope makes an angle of 15.1° with respect to the horizontal, how far along the hill did she slide on her sled?
A boy shoves his stuffed toy zebra down a frictionless chute. It starts at a height of 1.63 m above the bottom of the chute with an initial speed of 1.41 m/s . The toy animal emerges horizontally from the bottom of the chute and continues sliding along a horizontal surface with a coefficient of kinetic friction of 0.273 . How far from the bottom of the chute does the toy zebra come to rest? Assume ?=9.81 m/s2 .
Sometimes, steep roads going down have a small safety road by the side that goes up, which vehicules can use in an emergency, to slow down. A 3362.6 kg truck has lost its brakes coming down a mountain. Fortunately, there is a ramp of thick gravel inclined at 14 degrees that the driver can use to stop the truck. The truck hits the ramp moving at 20.58 m/s and then travels 35.6 meters up the ramp before it comes to a stop. What work is done by the gravel to stop the truck?
A woman at an airport is rolling her suitcase (mass = 20 kg) at an initial velocity of 1 m/s by pulling on a strap at an angle of 30° above the horizontal with a force of 33 N. The woman starts to speed up when she realizes that she is late for her flight. She pulls the suitcase over a distance of 50 m as she walks to her gate. What is the speed of the suitcase when she reaches her gate? (You can neglect friction in this problem. Give your answer in m/s.)
You are driving your car on a straight road with a coefficient of friction between the tires and the road of 0.55. A large piece of debris falls in front of your view and you immediate slam on the brakes, leaving a skid mark of 30.5 m (100-feet) long before coming to a stop. A policeman sees your car stopped on the road, looks at the skid mark, and gives you a ticket for traveling over the 13.4 m/s (30 mph) speedlimit. Draw the FBD of the car with complete details.
A 8.00-kg block of ice is released from rest at the top of a 1.60-m long frictionless ramp, slides downhill, reaching a speed of 3.25 m/s at the bottom. What is the angle between the ramp and the horizontal?
On a windy day, you decide to use a small homemade parachute to travel up a 7.4 degree hill on your frictionless rollerblades. You begin from rest at the bottom of the hill and travel a distance of 23 meters up the hill (measured along the incline), reaching a speed of 14 m/s. You have a mass of 60 kg. Determine the force the wind exerts on the parachute, assuming the force the wind exerts is parallel to the surface of the incline. Use conservation of energy.
