A truck with mass m has a brake failure while going down
an icy mountain road of constant downward slope angle a (Fig. ).
Initially the truck is moving downhill at speed v0. After careening
downhill a distance L with negligible friction, the truck driver steers the
runaway vehicle onto a runaway truck ramp of constant upward slope
angle b. The truck ramp has a soft sand surface for which the coefficient
of rolling friction is mr. What is the distance that the truck moves up the
ramp before coming to a halt? Solve by energy methods.

- Consider the incline shown in the figure with inclination angle θ and height h. The coefficient of kinetic friction between a block of mass m and the incline changes along its surface. From A to B it has a value of μ1, and from B to C its value is μ2. The block (not shown) is given an initial velocity up the incline at point A with a magnitude vA. A) What is the value of vA for which the block will reach the top of the incline (point C) with zero kinetic energy? Your answer should be written in terms of the quantities given in the statement. B) Show that for the block to surpass point B, the initial speed at A should satisfy the inequality vA > √[ (2/3)gh(1+μ1cotθ) ]During the investigation of a traffic accident, police find skid marks 150.0 m long. They determine the coefficient of friction between the car's tires and the roadway to be 0.500 for the prevailing conditions. Estimate the speed of the car when the brakes were applied.HW 11 Steep safety ramps are built beside mountain highways to enable vehi- cles with defective brakes to stop. A 10-ton truck enters a 15° ramp at a high speed vo 108 ft/s and travels for 6 s before its speed is reduced to 36 ft/s. Assuming constant deceleration, determine (a) the magnitude of the braking force, (b) the additional time required for the truck to stop. Neglect air resistance and rolling resistance. %3D RAIL INES 00 15°
- Time left 0:20:32 An amusement park in Dubai has a ramp which is frictionless. A child drops a smooth object and it slides down the ramp and comes down through a height 4 m. What distance is necessary to stop the object on the flat track if the coefficient of friction is 0.4? h. Answer:A large box of mass M is moving on a horizontal floor at speed v0. A small box of mass m is sitting on top of the large box. The coefficient of static friction between the two boxes is μs and coefficient of kinetic friction between the large box and floor is μk. Find an expression for the shortest distance dmin in which the large box can stop without the small box slipping.Two packages at UPS start sliding down the 20∘ ramp shown in the figure. Package A has a mass of 3.00 kg and a coefficient of kinetic friction of 0.220. Package B has a mass of 12.0 kg and a coefficient of kinetic friction of 0.170. How long does it take package A to reach the bottom?
- You are driving through the Ouachita Mountains at 12m/s. You see a maple-leaf oak (Quercus acerifolia) crossing the road and hit the brakes, 20m away. The coefficient of kinetic friction between your tires and the road is μ_k = 0.7. Will you strike this endangered broadleaf? Justify your answer with a calculation.Your final answer should be the distance you will travel before coming to a stop.A small boat is being pushed up a ramp into the back of a flatbed truck. The boat is sitting at the top of the ramp, which is located 1.4 m above the ground. The boaters think the boat is safe there, and begin to walkaway. However, they have neglected the thin layer of ice that has formed on the ramp, which is angled at 30◦ up from the ground. Neglecting the friction between the boat and the ramp, how long do the boaters havebefore the boat reaches the bottom of the ramp?Please tapy answer
