When rpm's get past 2500 car looses power and jerks until you get off the accelerator.

Ferris chases David. David has a head start of 12 cm and swims away at a constant speed of 1m/s. If Ferris, starting at rest, accelerates uniformly at 0.78 m/s^2, what is David's acceleration during the chase?

A 346 kg car is accelerating down an asphalt road. Between asphalt and rubber, the coeficient of static friction is 1.23 and the coefient of kinetic friction is .98 What is the fastest the car can accelerate?

A 4.10 kg block is pushed along the ceiling with an constant applied force of F = 78.5 N that acts at an angle = 53 with the horizontal, as in the figure below. The block accelerates to the right at 5.56 m/s2. Determine the coefficient of kinetic friction between the block and the ceiling.
