Q6: The 2.5-Mg pickup truck is towing the 1.5-Mg
car using a cable as shown. If the car is initially at
rest and the truck is coasting with a velocity of 30
km/h when the cable is slack, determine:
1. The common velocity of the truck and the car
just after the cable becomes taut.
2. The loss of energy.
[ Ans. (1) v2 = 5.21 m/s + , (2) AE = 36.6 kJ ]
30 km/h

2. Consider the following arrangement of masses: Mass 1 is connected to mass 2 by a very light string and moves over a frictionless pulley so that both masses move with the same speed and move the same distances (m₂ to the right a distance d and m₁ down a distance d). Assume m₁ 15 kg, m₂ 15 kg, and the coefficient of kinetic friction between m₂ and the table is k = 0.73. Let the masses start with an initial speed of 1.00 m/s. What is their speed after moving 1.00 cm (d = 0.0100 m)? - mq - -25 ms m1

3. Imagine building a large pendulum by attaching one end of a 3.25-meter-long cable to the ceiling and the other end to a bowling ball that weighs 64.5 N. If you pull the ball to the side, it will swing back and forth in a circular arc. In one experiment you measure the speed of the swinging ball to be 4.25 m/s as it passes through its lowest point (when the cable is vertical). At that moment, find a. the magnitude and direction of the ball's acceleration b. the tension in the cable
