Question 1 • POP Physics 26/27
A sled that has a mass of 8 kg is pulled at a 50 degree angle with a force of 20 N. The force of friction acting on the sled is 2.4 N. The free-body diagram shows the forces acting on the sled.
Answer
a
a = 1.3 m/s2; FN = 63.1 Na
a = 1.6 m/s2; FN = 65.6 Na
a = 1.9 m/s2; FN = 93.7 Na
a = 2.2 m/s2; FN = 78.4 N
