1. Determine the net force and acceleration for each object
as viewed from above. Assume that the mass of each
object is 5.0 kilograms.
2. A horse pulls a 300 kilogram carriage with a force F of
4000 newtons at an angle of 15° above horizontal. A
friction force of 2500 newtons acts on the carriage as the
horse pulls it.
a. Sketch and label the FOUR forces (Fg, FN, Ff and
F) acting on the carriage.
b. Calculate the net force acting on the carriage
and its resulting acceleration.
a.
[3N; 0.6 m/s2]
b.
F1 = 3 N
F1 = 50 N
F2 = 20 N
F1 = 25 N
F1 = 45 N
F2 = 16 N
