A 16-kg mass is placed on a 25° incline and friction keeps it from sliding. The coefficient of static friction in this case is 0.574 and the coefficient of sliding friction is 0.519 . The mass is given a shove causing it to slide down the incline. Taking down the incline as positive, what is the acceleration of the mass while it is sliding?
a. 0.47 m/s2
b. –0.47 m/s2
c. –0.96 m/s2
d. 0.96 m/s2
e. 14.50 m/s2
