Question

1. Make a sketch of the of the friction block sliding down the inclined track. Draw and label vectors Who indicate the direction of the velocity in the direction of the acceleration. Also sign a symbol to the mass of the block and label it on the drawing. 2. Draw free body diagram of the forces on the block as it slides on the ramp. Draw the acceleration vector for the block near the free body diagram. Choose a coordinate system and draw the force vectors on your coordinate system. What angles between your force vectors and your coordinate axes are the same as the angle between the ramp and the table? Determine all the angles between the force vectors and the coordinate axes. 3. Write down newtons second law in both the X and Y directions. For any forces that are at an angle to your coordinate system be sure to consider the components along the x and Y axes. Make sure all of your signs are consistent. 4. Using equations and step three determine an equation for the normal force and magnitude of the kinetic frictional force on the block. 5. If you increase the angle of the track does the normal force of the block increase or decrease? What happens to the kinetic frictional force? The normal force and kinetic frictional force can be also related using a coefficient of kinetic friction. What is this relationship? use the equation to schedule a graph of the magnitude of the kinetic frictional force on the block as a function of the magnitude of the normal force.
