A train has a mass of 455 tonne is going up an incline of 1 in 168. The tractive resistance of the train is 47.3 N/tonne. If the train accelerate uniformly from 23 km/h to 53 km/h in 1 minutes, calculate the total force applied by the engine.

The 250-lb pipe is being towed behind a truck, as shown in the figure. If θ = 25° and the coefficient of friction of the pipe with the ground is μk = 0.25, determine: a) the tension in the cable b) the acceleration of the truck

Consider the given pulley system. The rope is drawn towards the motor with a speed of 3 m/s. What is the speed of mass A and in what direction is it moving?

1. Two blocks are connected by a pulley system shown in the figure below. Neglect friction between the block on the left and the ramp sloped at angle 0. Suppose that the block on the left has mass m, and that the block on the right is moving downward at a constant speed v. m Given m, 0, and v, answer the questions below. (a) Find the mass of the block on the right? (b) Find the velocity of the block on the left. (c) If the block on the right was moving at a constant speed v upward, instead of downward, how would your answer to Question la change?

A constant tractive effort of 10 N is applied for 0.5 Hr, and total energy of 1 kWhr is consumed in doing so. Find the average velocity of the vehicle during this period.

The belt tension in the tight and slack sections is 25 N and 15 N, respectively. The belt operates at a speed of 10 m/s. How much power is delivered by the transmission system?

R ft Rft P lb The block of weight 131 lb is pushed with a force of P = 46 lb on top of two cylindrical rollers with a weight of 32 lb and a radius of R = 1.91 ft. Determine the block's speed after it has been moved 1.48 ft to the left. The block is originally at rest. No slipping occurs. Calculate your answer to two decimal places. Report your answer in ft/s.

A small box of mass m is placed on top of a larger box of mass 2m as shown in Figure. When a force is applied to the large box, both boxes accelerate to the right with the same acceleration. If the coefficient of friction (static/kinetic) between all surfaces is µ, what would be the magnitude of the force and what would be the acceleration ? 2m F O 1.
