In a railroad classification yard, a 66-Mg freight car moving at 1.1 m /s at A encounters a retarder section of track at B which exerts a retarding force of 27 kN on the car in direction opposite to motion. Over what distance x should the retarder be activated in order to limit the speed of the car to 2.7 m /s at C? 184 m 2.6 m А В (Vertical scale exaggerated) C

The figure shown below is released from rest with the spring unstretched. Use the datum shown for zero gravitational potential energy. For the values given below answer the following questions:Position 1 is Ha1 μk=0.14 k=32.5 Nm hA1=0.6 m mA=4.6 kg mB=1.3 kg What is the Gravitational Potential Energy for mass mA at position 1 (remember your signs)? What is the Gravitational Potential at position 1 for mB? What is the Potential Energy of the spring at position 1? What is the Kinetic Energy at position 1 for mA? What is the Kinetic Energy at position 1 for mB? Again we have the figure shown below that was released from rest with the spring unstretched. Use the datum shown for zero gravitational potential energy. At position 2 the spring is at its max stretch. Remember we have the values below; answer the following questions: μk=0.14 k=32.5 Nm hA1=0.6 m mA=4.6 kg mB=1.3 kg What is the max stretch in the spring?
RAIL LINES CROSS COUNTRY MOVERS OO 00 theta A 13,129-lb truck enters an emergency exit ramp at a speed of 112.4 ft/s. It travels for 7.9 s before its speed is reduced to 24.5 ft/s. Determine the braking force by the truck if the acceleration is constant. (Use Impulse-Momentum concepts.) Assume theta = 21.4 degrees Calculate your answer to two decimal places. Report your answer in pounds of force (lbf).

Q.
A 3.1 kg object is initially at rest and is experiencing a net force of magnitude 4.7e^-t/2 N. As time approaches infinity, notice that the net force decays toward 0 N, which tells us that the acceleration is also dropping to 0 m/s^2 (and so the velocity is leveling off to a terminal speed). What is the terminal speed? (Ans.= 3.0 m/s)
