Q1. A 291 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 0.90, and the log has the acceleration of 0.800 m/s2. Find out the tension in the rope.

Q2. A ranger in a national park is driving at 41km/h when a deer jumps onto the road 66 m ahead of the vehicle. After a reaction time of t s, ranger applies the brakes to produce an acceleration of -3.20m/s2. What is the maximum reaction time allowed if ranger is to avoid hitting the deer?
