Inclined plane Definition and 822 Threads

Suppose we have an inclined plane and 2 wheels. Both wheels have the same mass M but different radius R. So the only difference is that one is bigger than another. We put both wheels on the top of the inclined plane. They are in the same position, and then we let them go. I know that the wheel...

Homework Statement A block is projected up a 30° slope at 4m/s. When it is moving the coefficient of friction is 0.3. When the block is stationary the maximum coefficient of friction is 0.5. a. Calculate how far up the block will go. b. Show that the block will not remain there. c. Calculate...
