Q1. A jet plane lands with a speed of 102m/s and can accelerate at a maximum rate of 4.80 m/s2 as it comes to rest.
From an instant the plane touches the runway, what is the minimum time needed before it can come to rest?

Q2. A car is behind a truck going 25m/s on the highway. The car's driver looks for an opportunity to pass, guessing that his car can accelerate at 1.0m/s2. He gauges that he has to cover the 20-m length of the truck, plus 10m clear room at the rear of the truck and 10m more at the front of it. In the coming lane, he sees a car approaching, probably also travelling at 25m/s. he estimates that the car is about 400m away. Must he attempt the pass? Give Details.
