Q1. A ranger in a national park is driving at 44 km/h when a deer jumps onto the road 70 m ahead of the vehicle. After a reaction time of t s, the ranger applies the brakes to produce an acceleration of -3.00 m/s2. What is the maximum reaction time allowed if the ranger is to avoid hitting the deer?
Q2. A car travelling in a straight line has a velocity of +3.6 m/s. After an acceleration of 0.88 m/s2, the car's velocity is +8.4 m/s. In what time interval did the acceleration occur?
