A textbook with a mass of 2.18 kg is pulled across a table with a horizontal force of 5.5 N [E]. If the table has a coefficient of friction of 0.15, what is the acceleration of the textbook?

acceleration = 1.1 m/s2

Fnet = Fapplied - Ffriction

Fnet = mass*acceleration; Fapplied = 5.5 N; Ff  = μ*FNormal --> FNormal = Fgravity

Fnet = 5.5N - (0.15*9.81m/s2 *2.18kg) --> 5.5N - 3.21N

Fnet (m*a) = 2.29 N

accel = 2.29 N/mass -->  2.29 (kg*m/s2) /2.18kg  -->1.05 m/s2 --> rounds to 1.1 m/s2
