5. A block weighing 300. N is moved at constant speed over a horizontal surface by a force of 50. N applied parallel to the surface.
c. What would be the acceleration of the block if mk = 0? (answer: 1.63m/s^2)
6. A 10 kg block is allowed to slide down a 20 degree ramp with mk = 0.15.
a. What is the value of the frictional force opposing the block's slide down the ramp? (answer: 14N)
b. What is the acceleration of the block? (answer: 2 m/s^2)
