A motorist is traveling at $18.0 \mathrm{~m} / \mathrm{s}$ when he sees a deer in the road $38.0 \mathrm{~m}$ ahead. (a) If the maximum negative acceleration of the vehicle is $-4.50 \mathrm{~m} / \mathrm{s}^{2}$, what is the maximum reaction time $\Delta t$ of the motorist that will allow him to avoid hitting the deer? (b) If his reaction time is actually $0.300 \mathrm{~s}$, how fast will he be traveling when he hits the deer?

Late one night you are driving your car down the highway at 20 m/s when a deer steps onto the road 70 m in front of your car. If you apply the breaks at a deceleration of -3.2 m/s^2 , determine whether or not you will hit the deer. (Using a kinematic equation)

(part 1 of 2) A motorist traveling at 13 m/s encounters a deer in the road 46 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -6 m/s^2, what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Answer in units of s. (part 2 of 2) If his or her reaction time is 2.63513 s, how fast will (s)he be traveling when (s)he reaches the deer? Answer in units of m/s.
