A 25 n box is pulled across a frictionless surface by an applied force of 22 n. the coefficient of kinetic friction between the box and the surface is 0.3. find the acceleration of the box. use g = 10 m/s2 .

The acceleration of the box can be calculated using the formula:

Fnet = weight – friction

m a = m g – μk m g

where m is mass, a is acceleration, g is gravity, μk is the coefficient of kinetic friction

 

Simplifying the equation:

a = (1 – μk) g

a = (1 – 0.3) * 9.8 m/s^2

a = 6.86 m/s^2
