WebAssign


 * Sorry WebAssign appears to be down. Here are some of the questions are best I remember them. Hope it helps temporarily, at least.**

1. Given the mass and speed of a toy cart a given distance from the bottom of a ramp of a given angle theta, determine the distance along the ramp the cart will travel before coming to a stop. The coefficient of friction between the cart and the horizontal surface is give (mu) and the incline is frictionless.

2. Two blocks of mass m1 and m2 are connected by a rope (B). A second rope is attached to the block of mass m1 and a person exerts a constant force of a given magnitude. Determine (a) the acceleration of the system (b) the tension in rope A (c) the tension in rope B.

3. A block of mass m sits atop an incline of angle theta. Determine (a) the magnitude of the gravitational force between the block and Earth, (b) the magnitude of the normal force between the incline and the block, and (c) the magnitude of the frictional force between the block and the incline.

4. A block of mass m slides down an incline of angle theta at a constant speed v. Determine (a) the magnitude of the gravitational force between the block and the Earth, (b) the magnitude of the normal force between the block and the incline, (c) the magnitude of the frictional force between the block and the incline, and (d) the coefficient of kinetic friction between the block and the incline.


 * Sorry, these are the ones I have on this computer. Hopefully WebAssign comes back online soon.**
