Question

(14%) Problem 2: A block of mass m is initially at rest at the top of an inclined plane, which has a height of 4.9 m and makes an angle of ? = 24° with respect to the horizontal. After being released, it is observed to be traveling at v = 0.85 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is ?p = 0.1, and the coefficient of friction on the horizontal surface is ?r = 0.2. 50% Part (a) What is the speed of the block, in meters per second, just after it leaves the inclined plane? 50% Part (b) Find the distance, d, in meters.

Step 1

The initial potential energy of the block is m*g*h, where g is the acceleration due to gravity and h is the height of the inclined plane. As the block slides down the plane, this potential energy is converted into kinetic energy and work done against friction. The Show more…

Problem 2: A block of mass m is initially at rest at the top of an inclined plane, which has a height of 4.9 m and makes an angle of Θ = 24° with respect to the horizontal. After being released, it is observed to be traveling at v = 0.85 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1, and the coefficient of friction on the horizontal surface is μr = 0.2. Part (a) What is the speed of the block, in meters per second, just after it leaves the inclined plane? Part (b) Find the distance, d, in meters.
