Describe your experimental procedure. Perform the experiment and record the data. Estimate the uncertainty in each measurement. Use the mathematical procedure you devised to determine the coefficient of kinetic friction. Estimate the uncertainty in your result.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?
