Homework Statement Mass m whirls on a frictionless table, held to circular motion by a string which passes through a hole in the table. The string is pulled so that the radius of the circle changes from ri and rf. a) show that the quantity L = mr^2(d(theta)/dt) b) Show that the work in...

Here is a handdrawn version. I hope you can read it, but if not, please tell me. I then proceeded to have Tx = Fg. Thanks for the help .

thanks for the hint. it helped me realize that the initial mass's velocity in the x-direction is not zero at the top and then I solved the problem.

Homework Statement An instrument carrying rocket accidentally explodes at the top of its trajectory. The horizontal distance between the launch point and the point of explosion is L. The rocket breaks into two pieces that fly apart horizontally. The larger piece has three times the mass of the...

Thanks for all the help BvU. I have been trying to model this like a pendulum, however I have been trying for sometime and it seems that I am doing something wrong. Is this the right approach or is this completely wrong? Furthermore, my thinking is that the Tension in the X direction (back...

Thanks I did not know how to change the name of the thread. (I still don't despite attempting to look for the answer).

Homework Statement By what angle, in seconds of arc, will a plumbline be pulled out of its normal vertical direction by the gravitation attraction of a 10-ton that parks 20 ft away? Do you think that this effect could be detected? Homework Equations I think (G*m1*m2)/r^2 The Attempt at a...

I would think the force would come from Drag and that it would equivalent to T(sub0) since the forces must balance out. When the plane accelerates this force does not disappear. Therefore initial situation (constant v): Forces on Glider 1: T(ropeA) - (TropeB) - Force(drag) = 0 (1) Forces...

Homework Statement AP French Mechanics Problem 7-1 Two identical gliders, each of mass m, are being towed through the air in tandem. Initially they are traveling at a constant speed and the tension in the tow rope A is T(sub0). The tow plane then begins to accelerate with an acceleration A...
