Problem

A child pulls a

10\,\text{kg}

sled across level snow by applying a

60\,\text{N}

force at an angle of

30^{\circ}

above the horizontal. The coefficient of kinetic friction between the sled and the snow is

\mu_k = 0.20

. What is the magnitude of the sled’s acceleration? (a)

5.2\,\text{m/s}^2

(b)

4.0\,\text{m/s}^2

(c)

3.8\,\text{m/s}^2

(d)

2.6\,\text{m/s}^2
