- You are driving a car at a constant speed of 14.0 m/s along a straight level road. As you approach anintersection, the stoplight turns red and you slam on breaks and the wheels lock and you skid to a stop in25.0 m. What is the coefficient of kinetic friction between your tires and the road?Question 9. Traveling at a speed of 16.1 m/s, the driver of an automobile suddenly locks the wheels by slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.590. What is the speed of the automobile after 1.21 s have elapsed? Ignore the effects of air resistance. Ans: 9.1 m/sA crate starts from rest and slides 8.05 m down a ramp. When it reaches the bottom it is traveling at a speed of 5.55 m/s. If the ramp makes an angle of 23.0o with the horizontal, what is the coefficient of friction between the crate and the ramp?
- A cart coasts at a constant speed of 18.0m/s down a flat inclined road that makes an angle of 3.1° with the horizontal. What is the coefficient of friction between the cart and the road?A 0.30 kg puck is being pushed across a table with a horizontal force of 2.0 N. It starts from rest and is pushed for 13 seconds, ending with a speed of 1 m/s. Calculate the coefficient of friction μk between the puck and the table.The mass of a sports car is 1200 kg. The shape of the body is such that the aerodynamic drag coefficient is 0.250 and the frontal area is 2.20 meters squared. Ignoring all other sources of friction, calculate the initial acceleration the car has if it has been traveling at 100 km/h and is now shifted into neutral and allowed to coast.
- A person slides a bottle with mass 0.20 kg along a level table. It leaves his hand at 2.8 m/s and comes to a halt after going 1.0 m. Find the coefficient of kinetic friction between the bottle and the table.A block is placed on a wooden plank, which is initially horizontal. One end of the plank is slowly raised to make it more and more inclined, and for a while the block stays in place on the plank and doesn't slide due to static friction. Finally, when the plank reaches an incline of 56.3oabove horizontal, the block begins to slide. What is the coefficient of static friction between the block and the plank?While coasting a level section of the track, the speed of a 750kg bobsled decreases from 35m/s to 30m/s over a distance of 100m.
