A box slides down a 28.0 degree ramp with an acceleration of 1.25 m/s2. Determine the coefficient of kinetic friction between

Explanation:

From the question we are told that:

Angle

Acceleration

Generally the equation for Frictional force  is mathematically given by

Where

Since

Friction force is acting against move of box

Therefore

i believe the answer is a

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
