Describe quantitatively the motion of the system after the child is on the plank. Neglect friction with the ice. b. One point on the plank is at rest immediately after the collision. Where is it?

As shown in Figure 3(a), a wooden block B with mass mB = 2.4 kg on a rough inclined plane is connected to a massless spring ( k = 160 N/m ) by a massless cord passing over a pulley P of radius R = 0.25 m and mass Mp = 0.60 kg. The angle of the inclined plane is θ = 37∘ and the coefficients of static and kinetic frictions are μs = 0.35 and μk = 0.30 respectively. The frictional force at the axle of the pulley is negligible. The pulley can be regarded as a solid disk. (a) The system is at rest and in this case, block B is on the verge of sliding down. Figure 3(a) i. Indicate (with labeled arrows) the forces acting on the pulley and the block. ii. Calculate the tension in the string and the extension of the spring. (You can assume that the tensions in the cord on either side of the pulley P are the same for this part.) (b) As shown in Figure 3(b), another wooden block A of mass mA = 1.2 kg made of the same material as block B is released from rest. It slides down a distance l down the rough inclined plane and collides with block B. The two blocks stick together and move down the incline with a common velocity v = 0.80 m/s immediately after collision and the pulley rotates. The cord does not stretch and does not slip on the pulley. Figure 3(b) i. Determine the distance l. ii. Determine the acceleration of the two blocks at the moment they move down together and the pulley starts to rotate. iii. Determine how much further down the slope the two blocks move together after they collide before the two blocks come to a momentary rest.

An object of mass m starts from the left with velocity v0 and travels along a track moving right from position 1 to position 5 as shown. The track is completely frictionless, except for a horizontal region of length Δxf, where the coefficient of kinetic friction between the track and the object is μk. The object finally collides with a spring with a spring constant k and comes to rest in position 5 , compressing the formerly relaxed spring by a maximum amount, Δx. Which statements about the mechanical energy of the object-earth-spring system as the object moves from position 1 to position 5 is FALSE? Assume that the center of mass of the block is at the exact same vertical heights as positions 1, 3, and 5 . Note that while the object is moving at positions 1 through 4, the magnitudes of the velocity vectors shown may not be to scale. Note that more than more than one statement might be false (unlike what you will see on the final exam, where you will only be able to select a single response). The potential energy is the same at positions 1, 3 , and 5 . The gravitational potential energy is the same at positions 1, 3, and 5 . The total mechanical energy is the same at positions 1, 2, 3, 4, and 5. The kinetic energy is the same at positions 1 and 3 . The total mechanical energy is the same at positions 4 and 5 . The total mechanical energy is the same at positions 1, 2 , and 3.

A crane is made from a long, horizontal arm with mass m = 2.41×104 kg and length L = 52.0 m. The crane arm is supported by a vertical tower positioned halfway along the arm as shown in the figure below. The arm is free to rotate horizontally about the axis of the tower. The moment of inertia of a uniform rod with mass m and length L pivoted about its centre is given by Irod = 112 mL2. L Part 1) The crane lifts a mass M = 1070 kg at the end of the arm on one side of the tower. To keep the crane balanced, a counterweight of mass Mc = 5420 kg is placed on the arm on the opposite side of the tower to mass M. How far from the tower should the counterweight be placed such that the centre of mass for the arm and both masses is directly over the tower? x = m Part 2) What is the moment of inertia of the crane about the axis of the tower? Include the contributions of the horizontal arm, the mass and the counterweight. I = kg m2 Part 3) A net torque of magnitude τ = 6660 Nm is applied to the crane. If the crane starts at rest, what is its angular velocity after t = 30.0 s ? ω = rad s−1
