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 body of mass 5 kg is acted upon by two perpendicular forces 8 N and 6 N. Give the magnitude and direction of the acceleration of the body.
