A block of mass m=3.0 kg is pushed down a 50° incline surface with a force of magnitude F=40 N.
a. Find the acceleration of the block if the incline is frictionless.
b. Calculate the acceleration if the same force is applied on a horizontal frictionless surface
c. Calculate the acceleration if a mass of 10kg is used
d. Is the acceleration smaller / greater / equal to acceleration? Explain your answer.
