A 8000 kg engine pulls a train of 5 wagons, each of 2000 kg, along a horizontal track. If the engine exerts a force of 40000 N and the track offers a friction force of 5000 N, then calculate:
the acceleration of the train.

A 8,000 kg engine pulls a train of 5 wagons, each of 2,000 kg along a horizontal track. If the engine exerts a force of 40,000 N and track offers a force of friction of 5,000 N, then calculate the :force of wagon 1 on wagon 2.

A train of 150 metre ton is drawn up a rough inelined plane of 1 in 100 at the rate of 36 km. if the frictional force is 12 N ton^-1 ,calculate the power of the engine.

A constant force of 15 N acts on a body of mass 5 kg. Find the acceleration produced.

A rope of negligible mass is wound round a hollow cylinder of mass 3 kg and radius 40 cm. What is the angular acceleration of the cylinder if the rope is pulled with a force of 30 N ? What is the linear acceleration of the rope ? Assume that there is no slipping.
