A student moves a box of books down the hall

by pulling on a rope attached to the box. The

student pulls with a force of 174 N at an angle

of 35.0 above the horizontal. The box has a

mass of 25.1 kg, and μk between the box and

the floor is 0.25.

The acceleration of gravity is 9.81 m/s2 .

Find the acceleration of the box.

Answer in units of m/s2 ...?

Working formula for both problems is Newton's 2nd Law of Motion, i.e.,

F = ma

where

F = net force acting on a body
m = mass of the body
a = acceleration of the body

For Problem #1 ---

The working formula is

F = 174(cos Θ) - µmg = ma

where

Θ = angle at which force is pulling = 35 deg
µ = 0.25
g = acceleration due to gravity = 9.8 m/sec^2 (constant)

and all other terms have been previously defined.

Substituting appropriate values,

174(cos 35) - 0.25(25.1)(9.8) = 25.1a

Solving for "a"

a = 8.71 m/sec^2
