Consider a flat-bed truck whose mass, including its contents, is supported equally by its four tires. Assume the truck has four-wheel drive, so the drive train translates the power of the motor equally to all four wheels. The mass of just the truck is m2, and the coefficient of static friction between the tires and the road is μs. A metal crate of mass m1 sits on the flat, horizontal, wooden bed of the truck, and μk is the coefficient of kinetic friction between the bed and the metal crate.
Part (b) Assume the crate slips in the bed of the truck as the truck is accelerating. Write an expression for the maximum possible acceleration of the truck so that its tires don't slip.

A new safe is being delivered to the Corner Book Store. It is to be placed in the wall at a height of 1.5 m above the floor. The delivery people have a portable ramp, which they plan to use to help them push the safe up and into position. The mass of the safe is 510 kg, the coefficient of static friction along the incline is m s = 0.42, and the coefficient of kinetic friction along the incline is m k = 0.33. The ramp forms an angle q = 15 ° above the horizontal. (a) How hard do the movers have to push to start the safe moving up the incline? Assume that they push in a direction parallel to the incline.(b) To slide the safe up at a constant speed, with what magnitude force must the movers push?

- Sally wants to hang up some decorations on the side of her house, so she props up a ladder of length L = 3m against a wall at an angle of θ = 50° with respect to the horizontal. The ground is somewhat icy, where the coefficient of static friction between the ground and the ladder’s feet is µ = 0.55; while the wall of her house can be considered frictionless. If Sally has a mass of 60kg and the ladder has a mass of 80kg, what is the max distance that she can climb up the length of the ladder without it slipping? You may assume the ground is perfectly flat, and the wall is perpendicular to the ground.arrow_forwardBank robbers have pushed a 1000 kg safe to a third-story floor-toceiling window. They plan to break the window and lower the safe 10.0 m to their truck. Not being too clever, they stack up 500 kg of furniture, tie a rope between the safe and the furniture, and place the rope over a pulley. Then they push the safe out of the window. The coefficient of kinetic friction between the furniture and the floor is 0.5. The rope would break if the force on it exceeds 5000 N. a) Does the rope break? b) What is the acceleration of the safe? c) What is the safe’s speed when it hits the truck?arrow_forwardAn airplane of mass 3.60 × 105 kg experienced a problem with all its tires when it was about to touch down at a runway of an airport. The tires were deadlocked and not able to roll. The airplane began to skid once it touched down and left behind a 728 m long skid mark on the runway before it came to a stop. Even though everyone on the airplane was safe, the pilot was accused of failing to land the airplane within the allowable speed limit of 80.0 m/s and his pilot license was suspended. Given that the coefficient of kinetic friction between the tires and runway was 0.496. (i) Determine the work done by friction on the tires.(ii) Use the Work-Energy Theorem to evaluate if the suspension of the pilot’s license should be revoked. #This is an exercise question, please help.

- A refrigerator is at rest on a level floor. Attempting to slide it across the floor, you exert a horizontal pushing force P at a height y above the floor, as in the figure. If y is too large, the refrigerator will tip instead of sliding. Find the largest value of y that makes the refrigerator slide without tipping if its mass is M = 119 kg, its center of mass is located where d = 0.49 m and h = 1.05 m, and the coefficient of static friction between the refrigerator and the floor is μs = 0.26. [Hints: Use the equilibrium conditions to place the refrigerator on the verge of both sliding and tipping (but not doing either). When the refrigerator is on the verge of tipping, the normal force will act at its lower front corner.] y = P Y m M cm- h ←d→arrow_forwardA refrigerator is at rest on a level floor.

- A student is attempting to push his stalled car out of an intersection with his girlfriend at the wheel. The car and girlfriend has a combined mass of m = 999 kg. Unfortunately the hill has an incline of θ = 3.6 degrees with respect to the horizontal. The student can supply a force of F = 883 N for t = 24 s before tiring. What is the furthest the edge of the intersection can be d in meters from the stalled car in order to make it out in one push. Assume no rolling resistance from the car and that his girlfriend brakes to bring the car to a stop when he stops pushing. I got these hints: -Start with free body diagram.

The roof is pitched such that it rises 6 inches for every 12 inches of horizontal run. As you turn to go down the ladder, you accidentally knock into the toolbox. The box slips down the roof and lands on the ground below approximately 3.5 ft from the house. If the weight of the toolbox is 5 lb, the roof height is 9 ft, and the total house height is 30 ft, what is the coefficient of kinetic friction between the toolbox and the roof?arrow_forwardA small block sits at one end of a flat board that is 4.00 m long. The coefficients of friction between the block and the board are μs= 0.450 and μ = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0, and then the block starts to slide down the board. If the angle is kept equal to α0 as the block slides, what is the speed of the block when it reaches the bottom of the board? Express your answer with the appropriate units.arrow_forward
- A small box with a weight of 35.0 N is placed on top of a larger box that has a weight of 80.0 N.
