Q1. A ranger in a national park is driving at 52 km/h when a deer jumps onto the road 86 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -2.9 m/s2.

What is the maximum reaction time al- lowed if the ranger is to avoid hitting the deer?

Q2. A passenger standing in the lounge notes that she must lean inward to keep from falling. Let an angle leaning inward be positive and outward be negative.

At what angle from vertical must she lean? Because radius of the curve is much greater than the height of the passenger, neglect torques. 1 mile = 5,280 ft.
