Homework Statement If both k of the spring and m are doubled while the damping constant b and driving force magnitude F0 are kept unchanged, what happens to the curve, which shows average power P(ω)? Does the curve: a) The curve becomes narrower (smaller ω) at the same frequency; b) The curve...

So then do I just need to set P initial to P final, and solve for d, without having to worry about angular momentum?

Homework Statement A rod of mass M and length L rests on a frictionless table and is pivoted on a frictionless nail at one end. A blob of putty of mass m approaches with velocity v from the left and strikes the rod a distance d rom the end as shown, sticking to the rod. 1. Find the angular...

Homework Statement A small block with mass m is sitting on a large block of mass M that is sloped so that the small block can slide down the larger block. There is no friction and no drag force. The center of mass of the smal block is located a height H above where it would be if it were...

So at the top, we have a normal force pushing the ball up, and at the bottom, a tension force pulling the ball?

Homework Statement A ball of mass m is attached to a massless rod and is suspended from a frictionless pivot. It is moving in a vertical circle or Radius R such that it has speed v1 at the bottom. The ball is in a vacuum. Find an expression for the force exerted by the rod at the top of the...

Block on a Plane -- Friction problem edit: deleted

Homework Statement A model rocket blasts off vertically from rest at time t=0 being pushed by an engine that produces a constant thrust force F up. The engine blasts away for t seconds and then stops. Find the height y and vertical velocity that the rocket has reached by the end of the blast...
