1 poA cart of weight W is lifted up at constant speed by a steel cable attached to an electric pulley.Assuming there is no resistive forces and the mass of the steel cable is negligible compared to themass of the cart, what can we conclude about the force T. exerted by the cable on the cart?T=W, T is directed upwardT

given speed = constant so accleration = 0

A freight train consists of two 8.00104 -kg engines and 45 cars with average masses of 5.50104 kg. (a) What force must each engine exert backward on the track to accelerate the train at a rate of 5.00102 m/s2 if the force of friction is 7.500105 N, assuming the engines exert identical forces? This is not a large frictional force for such a massive system. Polling friction for trains is small, and consequently trains are very energy-efficient transportation systems. (b) What is the force in the coupling between the 37th and 38th cars (this is the force each exerts on the other), assuming all cars have the same mass and that friction is evenly distributed among all of the cars and engines?
