A 1340 kg car has just passed a diner. The closest the car came to the diner was R = 40.5 m, but the car has driven another x = 36.7 m in the 2.85 s elapsed since then. If the car travels at constant speed, what is the current magnitude L of the angular momentum of the car about the diner? L = kg⋅m2/s

A jetliner of mass 20,000 kg is flying over level ground at a constant altitude of 4.30 km with a constant velocity of 155 m/s west. Its direction is currently straight toward the top of a mountain. At a particular instant, a house is directly below the plane at ground level. (a) At this instant, what is the magnitude of the plane's angular momentum relative to the house (in kg⋅m2/s )? kg⋅m2 /s (b) As the plane continues its constant velocity motion, how does the angular momentum vector relative to the house change? The magnitude of the angular momentum vector stays the same, but the direction changes. Both the magnitude and direction of the angular momentum vector change. The direction of the angular momentum vector stays the same, but the magnitude changes. Both the magnitude and direction of the angular momentum vector stay the same. (c) At this same instant, what is the magnitude of the plane's angular momentum relative to the mountaintop (in kg⋅m2 /s )? kg⋅m2/s

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
