A 216-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp.?

Question

The ramp is inclined at 34.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.810, and the log has an acceleration of 0.700 m/s2. Find the tension in the rope.

Answer 1

net force equals mass times acceleration

216*0.700=T-216*9.81*(sin(34)-
0.810*cos(34))

solve for T

2759 N
