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.
Standing at a crosswalk, you hear a frequency of 520 Hz from the siren of an approaching police car. After the police car passes, observed frequency of the siren is 455 Hz. Establish the car's speeds from these observations.

You (height of your eyes above the water, 1.75) are standing 2.00 from the edge of a 2.50--deep swimming pool. You notice that you can barely see your cell phone, that went missing a few minutes before, on the bottom of the pool.
If you now place a pencil under the edge of the mirror nearer the wall, tilting it upward by 5.0, how much higher on the wall is the spot?
