- A 7.80-g bullet moving at 600 m/s penetrates a tree trunk to a depth of 4.80 cm. (a) Use work and energy considerations to find the average frictional force that stops the bullet.N(b) Assuming the frictional force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving.Q30The work required by Neymar to push a box of soccer balls on a horizontal, frictionless floor to accelerate it from a speed of zero to v is W1. The work required by Neymar to accelerate the box of soccer balls on the same floor, from v to 2v is W2. The ratio of W2 to W1 is The correct answer is 3 but I don't know how they got to that answer
- You may have noticed runaway truck lanes while driving in the mountains. These gravel-filled lanes are designed to stop trucks that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 40.0 m long. Think of the ground as exerting a frictional drag force on the truck. A truck enters a typical runaway lane with a speed of 59.0 mph ( 26.4 m/s ). Use the work-energy theorem to find the minimum coefficient of kinetic friction between the truck and the lane to be able to stop the truck.A 7.80-g bullet moving at 470 m/s penetrates a tree trunk to a depth of 5.60 cm.(a) Use work and energy considerations to find the average frictional force that stops the bullet.N (b) Assuming the friction force is constant, determine how much time elapses between the moment the bullet enters the tree and the moment it stops moving.sUsing the work-energy theorem to investigate a traffic scene A car hit a pedestrian and immediately the driver slammed on the brakes to stop the car. During the subsequent trial, the driver's lawyer claimed his client was obeying the posted 35-mi/hr speed limit. You have been called in as the state's expert witness. Your investigation of the accident found that the skid marks made while the brakes were applied until the car stopped were Ax = 94 m long. You also measured the coefficient of kinetic friction between the car's tires and the road (using a drag sled) to be μk = 0.36. (a) Use the work-energy theorem to show that the car's minimum speed vo when the driver slammed on the brakes is given by vo = √2 μg Ax (b) Use the result of part (a) to determine if the car was speeding when the pedestrian was hit. [answer: The car's speed was at least 57 mi/hr when the brakes were applied.] (c) If the car's mass is 1470 kg, how much heat energy was produced while the car was skidding? [answer:…
- Starting from rest at t = 0, a 5.0-kg block is pulled across a horizontal surface by a constant horizontal force having a magnitude of 12 N. If the coefficient of friction between the block and the surface is 0.20, at what rate is the 12-N force doing work at t = 5.0 s? 26 kW 0.12 kW 0.14 kW 12 kW 0.13 kWA-C please!A 2.46 kg block moves along a frictionless surface with a speed of 7.83 m/s when it encounters a rough shallow hill, whose sides have a length of l=5.21 m. The hill is low enough so that the block can make it over the hill. Because the surface of the hill is rough (shown in orange in the figure), the block experiences a frictional force of 2.23 N while on the hill. a) What is the speed of the block after it traverses the hill?
- A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. 1.Enter an expression for the minimum angle θ (in degrees) the box will begin to slide. 2.Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is large enough that it will move down the plank. 3.For a plank of any length, at what angle θ (in degrees) will the final speed of the box at the bottom of the plank be 0.85 times the final speed of the box when there is no friction present? Assume μk = 0.39.A daredevil on a motorcycle leaves the end of a ramp with a speed of 32.4 m/s as in the figure below. If his speed is 30.5 m/s when he reaches the peak of the path, what is the maximum height that he reaches?
