A box (350 kg) sits inside the trailer of a semitruck traveling at a speed of 15 m/s (~ 33 mph). Suddenly, a car in front of the truck stops in the road. The driver of the truck hits the brakes to bring the truck to a stop. Assume that the coefficient of static friction µs = 0.7 between the box and the floor of the trailer. Assume g = 10 m/s2. When the truck is slowing down, what is...

2. (25 points) One hauling truck is traveling on a level road. The driver suddenly applies the brakes, causing the truck to decelerate by an amount 9/3. This causes a box in the rear of the truck to slide forward. If the coefficient of sliding friction between the box and the trucked is 1/4, find the acceleration of the box relative to the truck.

As you are driving down a road at 110.0km/h when you see a deer jump out in front of you. If you immediately slam on the brakes determine your stopping distance if the static coefficient of friction is 0.995 and the kinetic coefficient of friction is 0.789 if: a. Your wheels lock; (2pts) b. Your wheels continue to turn. (2pts) c. Explain why this shows that anti-lock braking systems are an important 8) 5 safety feature in modern vehicles. (1pt)...

Picture taken from problem 13-35. A 2000 kg truck is traveling at 25 meters/second. The driver suddenly hits the brakes, causing the truck to slide on the road. The coefficient of friction between the truck and the road is fk = 0.32. Determine the distance the truck slides. (Notice: the box is irrelevant in this problem)

020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

a car is traveling at a constant speed of Vo on a straight, level road. After the brakes are applied at t=0 seconds, the motion can be approximated by: x=t^3/100-t^2 +17t where x is the distance traveled in meters and t is the time in seconds. Determine: A the initial velocity (Vo), B. the time required for the car to stop, C. The distance required for the car to stop, and D. The maximum deceleration during braking.

A car is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53. (a) Find the acceleration of the car. (Take down the ramp to be the positive direction) (b) How long does the car take to skid to a stop if its initial speed is...
