Concept explainers
Consider a large truck carrying a heavy load, such as steel beams. A significant hazard for the driver is that the load may slide forward, crushing the cab, if the truck stops suddenly in an accident or even in braking. Assume, for example, that a 10 000-kg load sits on the flatbed of a 20 000-kg truck moving at 12.0 m/s. Assume that the load is not tied down to the truck, but has a coefficient of friction of 0.500 with the flatbed of the truck. (a) Calculate the minimum stopping distance for which the load will not slide forward relative to the truck. (b) Is any piece of data unnecessary for the solution?

- If the vector components of the position of a particle moving in the xy plane as a function of time are x(t)=(2.5ms2)t2i and y(t)=(5.0ms3)t3j, when is the angle between the net force on the particle and the x axis equal to 45?arrow_forwardThe x and y coordinates of a 4.00-kg particle moving in the xy plane under the influence of a net force F are given by x = t4 6t and y = 4t2 + 1, with x and y in meters and t in seconds. What is the magnitude of the force F at t = 4.00 s?arrow_forwardA 10000-kg load sits on the flatbed of a 20000-kg truck moving at 12.0 m/s. Assume that the load is not tied down to the truck, but has a coefficient of static friction of 0.500 and a coefficient of kinetic friction of 0.400 with the flatbed of the truck. If the truck needs to stop in 10.0 m with constant acceleration, what is the force of friction between the load and the truck when the brake is first applied?arrow_forward
- A pickup truck is carrying a 10.0 kgkg toolbox, but the tailgate of the truck is missing, so the box can slide out if it starts moving. The coefficients of static and kinetic friction between the toolbox and the truck bed are 0.34 and 0.15, respectively. Assume that the truck bed is horizontal. What is the shortest time the truck could take to accelerate from rest to 9.60 m/sm/s without causing the toolbox to slide?arrow_forwardA 3 kg and a 5 kg box rest side-by-side on a smooth, level floor. A horizontal force of 32 N is applied to the 3 kg box pushing it against the 5 kg box, and, as a result, both boxes slide along the floor. What is the magnitude of the contact force between the two boxes? Assume no friction.arrow_forwardA car traveling at 56 km/h hits a bridge abutment. A passenger in the car moves forward a distance of 56 cm (with respect to the road) while being brought to rest by an inflated air bag.

- A crate rests on the flatbed of a truck that is initially traveling at 15 m/s on a level road. The driver applies the brakes and the truck is brought to a halt in a distance of 38 m. If the deceleration of the truck is constant, what is the minimum coefficient of friction between the crate and the truck that is required to keep the crate from sliding?arrow_forwardA car traveling at 53 km/h hits a bridge abutment.A passenger in the car moves forward a distance of 65 cm (with respect to the road) while being brought to rest by an inflated air bag.What magnitude of force (assumed constant) acts on the passenger’s upper torso, which has a mass of 41 kg?arrow_forwardA large wrecking ball of mass m is resting against a wall. It hangs from the end of a cable that is attached at its upper end to a crane that is just touching the wall. The cable makes an angle of θ with the wall. Ignoring friction between the ball and the wall, find the tension in the cable.arrow_forward
- Two children are pulled on a sled over snow-covered ground. The sled is pulled by a rope that makes an angle of 35° with the horizontal. The children have a combined mass of 45 kg and the sled has a mass of 5.0 kg. The coefficients of static and kinetic friction are u, = 0.20 and µ, = 0.15. Calculate the maximum possible force of static friction between the sled and snow. If the tension in the rope is 95 N, will the sled move?

The kinetic friction coefficient between the upper and lower block is 0.440. The kinetic friction coefficient between the lower block and the flat surface is 0.140. A horizontal force F= 97 N pushes against the upper block, causing it to slide. The friction force between the blocks then causes the lower block to slide also.

The bottom block is sitting on a horizontal floor. The coefficient of static friction between the blocks is μs1, and the coefficient of static friction between the bottom block and the floor is μs2. What is the minimum pull force F on the bottom block so that the blocks begin to move? Given that the coefficient of kinetic friction between the bottom block and the floor is μk, what is the maximum pull force F so that there is no slipping between the blocks?arrow_forward
