Q1. A ranger in a national park is driving at 24.0 mi/h when a deer jumps into the road 270 ft ahead of the vehicle. After a reaction time of t, ranger applies the brakes to produce an acceleration of a = -9.00 ft/s2. What is the greatest reaction time allowed if she is to avoid hitting the deer?

Q2. A crate of mass = 32 kg rides on the bed of a truck attached by a cord to the back of the cab. The cord can withstand a maximum tension of 68 N before breaking. Neglect friction between the crate and the truck bed; find out the maximum acceleration the truck can have before the cord breaks.
