Question

A mass is pushed over a surface by a 19 N force that acts somewhat downward at an angle of θ = 45° to the horizontal as shown in the figure below. The mass is 3.0 kg and the coefficient of friction between the mass and surface is 0.25.

(a)What is the magnitude of the frictional force on the mass from the surface?
N
(b) What is the magnitude of the acceleration of the mass?
