The right side of a truck has a constant speed of 6 m/s as it turns to the left on a path with of curvature of 16 m. The direction of the angular velocity vector of the rear right wheel is changing as the truck turns. What is the magnitude and direction (relative to the truck) of the angular acceleration vector, α→, of the rear right wheel?

(a) In a minor rail yard accident, a runaway goods truck of mass 1.85×104 kg collides at u = 20.0 ms−1 with a stationary truck of mass 2.20×104 kg, as shown in Figure 3. The trucks lock together and travel at the same speed after the collision. Assume friction is negligible. Figure 3 Sketch of the runaway and stationary goods trucks, for use in Question 10. (i) Show that the speed of the trucks after the collision is 9.14 ms−1. (ii) One of the truck wheels can be modelled as a solid disk of radius 4.60×10−1 m and moment of inertia 36.5 kgm2. Calculate the magnitude of the wheel's angular momentum after the collision. (iii) The truck's linear velocity vector is in the positive x-direction using the Cartesian coordinate system shown in Figure 3. What is the direction of the wheel's angular momentum vector? Briefly explain your reasoning. (b) The train driver sounds the train's whistle. The whistle is a pipe that is open at one end and closed at the other, and it has a length of 0.480 m. The speed of sound in air is 343 ms−1. (i) Sketch the standing wave pattern of the air pressure in the whistle for its fundamental resonant frequency. Clearly indicate the open and closed ends of the whistle pipe. (ii) Hence calculate the frequency of the sound made by the whistle's fundamental resonance. (c) An observer standing on a bridge above the train track hears the whistle as the train approaches at a speed of 40.0 ms−1. (i) Show that the whistle frequency perceived by the observer is 13.2% greater than the frequency perceived by the driver. (ii) Describe how the sound of the whistle, as heard by the observer, will change as the train approaches and goes past the bridge.

A farm truck moves due east with a constant velocity of 8.80 m/s on a limitless, horizontal stretch of road. A boy riding on the back of the truck throws a can of soda upward (see figure below) and catches the projectile at the same location on the truck bed, but 19.0 m farther down the road. (a) In the frame of reference of the truck, at what angle to the vertical does the boy throw the can? ∘ (b) What is the initial speed of the can relative to the truck? m/s (c) What is the shape of the can's trajectory as seen by the boy? a straight line segment upward and then downward a symmetric section of a parabola opening downward An observer on the ground watches the boy throw the can and catch it. (d) In this observer's frame of reference, describe the shape of the can's path. a straight line segment upward and then downward a symmetric section of a parabola opening downward (e) In this observer's frame of reference, determine the initial velocity of the can. magnitude m/s direction ० above the horizontal eastward line
