Q. A massive cable is attached to a 75.0 kg mass on a frictionless surface and a horizontal force of magnitude F accelerates the arrangement as shown in Figure P.52. If the force of the cable on the mass has a magnitude 0.800F, what is the mass of the cable?

Q. A train starts at rest at a station and accelerates at a rate of 2.0 m/s^2 for 20 seconds. Then, this train runs at a constant speed for 100 seconds and slows down at a rate of 5.0 m/s^s until it stops at the next station. Calculate the total distance covered by the train.
