Q1. Show a analyse to find the time in years that it would take to travel to (relatively) nearby Barnard's star (which is 6.01 light-years away) travelling at the velocity of a jet airliner (1000 km/hr).
Q2. A car is travelling at 30.0 km/h on a flat highway.
(a) If the coefficient of friction between road and tires on a rainy day is 0.120, what is the minimum distance in which the car will stop?
(b) What is the stopping distance when the surface is dry and the coefficient of friction is 0.500?
