Q1.An automobile driver puts on brakes and decelerates from 68 mph to zero in 16 s. What distance does the car travel?

A car dealer claims that his product will accelerate at a constant rate from rest to a speed of 200 km/hr in 8s. What estimated distance will the car travel?

Q2. A police car going 25 mph spots a speeding car going at 85 mph and 200 feet ahead of him. The police car accelerates at 25 ft/s2. The reaction time of the police car is 0.8 seconds. How many total seconds will it take the police to reach speeding car and how numerous miles from his/her starting position will the police car have travelled by the time he reaches the speeding car and what is the police car's velocity? Reply the similar questions, if 2 seconds after the police accelerates, the speeding car also accelerates at 10 ft/s2.
