Out: A driver of a car traveling a 15 m/s slows  down with an acceleration of -2 m/s 2 .  How  long does it take the car to get to a final  speed of 10 m/s?
A car traveling initially at 7.0 m/s accelerates  uniformly at the rate of  0.80 m/s 2  for a distance  of 245 m. What is its velocity at the end of the acceleration?

Unformatted text preview: An aircraft has a liftoff speed of 33 m/s. What minimum constant acceleration does this require if the aircraft is to be airborne after a take-off run of 240 m? A car with an initial speed of 4 m/s accelerates at a uniform rate of 1 m/s 2 for 50m . Find the final velocity. A driver of a car traveling a 15 m/s slows down with an acceleration of -2 m/s 2 . How far does it go when the final speed is 10 m/s?...
