Joyce Morse · Answer 1

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
