An object, at time equal zero, has a velocity of 2.0 m/s and constant acceleration of 3.08 m/s².
How far does it travel in 8 seconds?
Do not write the units in your answer, but your answer should be in meters.
A turtle and a rabbit engage in a footrace over a distance of 4km. The rabbit runs 0.5km and then stops for a 90-min nap. Upon awakening, he remembers the race and runs twice as fast. Finishing the course in a total time of 1.75h, the rabbit wins the race. Calculate the average speed of the rabbit
A car starts from rest and accelerates at a constant 10 m/s2 during aquarter-mile (402 m) race. How fast is the car going at the finish line?
I know the answer to this problem is 90 m/s, but I don't know how the book i found it in came to this answer. How am I supposed to solve this problem without knowing either final velocity or time?
