Q1. A 485 kg sailboat has an acceleration of 0.50 m/s2 at an angle of 51° north of east. Find magnitude and direction of a net force that acts on the sailboat.
Q2. A 258-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.980, and the log has an acceleration of 0.760 m/s2. Find the tension in the rope.
