Question
17b is supposed to say “How would the magnitude of A) change..”


17. A dart of mass is fired at a speed m towards a bicycle of mass as shown on the right. The dart hits the tire at the edge and becomes embedded in it, causing the tire to rotate. The wheel has a radius and a moment of inertia given by a) Determine an expression for the angular speed of the tire after the dart strikes. b) How would the magnitude of b) change if the wheel had the same mass., but a smaller radius and the dart were to hit at the same speed at the edge? Justify your answer qualitatively in a single sentence.

    A bicycle wheel of mass M and radius R is placed on a vertical axle and is able to rotate without friction. A dart of mass, m is fired toward the wheel with an initial velocity v(o). The dart strikes the wheel and sticks in the tire. The moment of inertia of the wheel is I=mr^2. What is the initial angular momentum of the dart with respect to the center of the wheel? What is the angular velocity of the...

    A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
