Please help with BOTH parts.
[1] A driver of a car of mass 1000 kg, initially moving at 25 m/s, slams on his breaks to avoid a family of ducks crossing the road. His tires lock and the car begins to skid. The coefficient of kinetic friction between the tires and the road is ' K = 0.5 . (a) How far does the car slide before coming to rest? (b) How much heat is generated by the friction during...

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...

2. A 1500 kg car is traveling at 25 m/s up a 12° incline when it runs out of gas. The values of Hand uk between the tires of the car and the road are 0.02 and 0.3 respectively. a. Draw clearly the free-body diagram and the motion diagram of the car from the moment it runs out of gas to the moment it comes to a stop. The x-axis should be up the incline. b. Calculate the net force...

The driver of one car has a mass of 1200 kg and is traveling at 10 m/s westward when he collides with another car with a mass of 2000 kg that is traveling 15 m/s northward. The two cars stick together after colliding. Please show all work. a) What is the total momentum before the collision and after the collision? b) What are the speed and direction of the cars after the collision? c) If coefficient of kinetic friction between...
A 1,200-kg car is traveling on an icy horizontal road at 30 m/s. The maximum rate...
A 1,200-kg car is traveling on an icy horizontal road at 30 m/s. The maximum rate at which the car can decelerate without sliding on the ice is 1.2 m/s2; reaching this value will immediately result in sliding uncontrollably with a reduced sliding friction of 700 N. If the driver panics and slams hard on the brakes, then how far will the car slide before stopping? Answer in km.

A 2000 kg car is traveling at 45 m/s. A force of 4000 N is applied to the breaks of the car as it slows down to 15 m/s. How far does the car travel as it slows down? please show all math steps and how you set up the equations. Thanks!

The driver of a 1.19 103 kg car traveling on the interstate at 35.0 m/s (nearly 80.0 mph) slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead. After the brakes are applied, a constant kinetic friction force of magnitude 7.96 103 N acts on the car. Ignore air resistance. (a) At what minimum distance should the brakes be applied to avoid a collision with the other...

A car of mass 875 kg is traveling 30.0 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.60 s in the positive -direction before coming to rest. (a) What is the car's acceleration? (b) What magnitude force acted on the car during this time? (c) How far did the car travel? [Ans: ()-536 m/s (b) 4690 N(c) 84,0 m]

A 1890 kg car traveling at 13.3 m/s collides with a 2970 kg car
that is initally at rest at a stoplight. The cars stick together
and move 1.96 m before friction causes them to stop. Determine the
coefficient of kinetic friction between the cars and the road,
assuming that the negative acceleration is constant and all wheels
on both cars lock at the time of impact.
