A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass of 1000.0 kg, and the car has a mass of 100.0 kg. The engine exerts a force F on the track, and the track exerts a force F on the engine that is directed in the direction of motion of the train. This force F is what powers the train. What is the tension T in the cable? Use g = 9.8 m/s^2.
a. 980. N
b. 0.00 N
c. 10.2 N
d. 98.0 N
What is the force F that is powering the train?

An air-track glider of mass 0.100 kg is attached to the end of a horizontal air track by a spring with force constant 20.0 N/m. Initially the spring is unstreched and the glider is moving at 1.50 m/s...
An air-track glider of mass 0.100 kg is attached to the end of a horizontal air track by a spring with force constant 20.0 N/m. Initially the spring is unstreched and the glider is moving at 1.50 m/s to the right. With the air track turned off, the coefficient of kinetic friction is μk=0.47. It can be shown that with the air track turned off, the glider travels 8.6 cm before it stops instantaneously. How large would the coefficient of...

A freight train consists of two kg 1000.8 4 − × engines and 45 cars with average masses of kg 1050.5 4 × . (a) What force must each engine exert backward on the track to accelerate the train at a rate of 2 –2 m/s 10.005 × if the force of friction is N 1050.7 5× , assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Rolling friction for trains...
