1)Two boats start together and race across a 48-km-wide lake and back. Boat A goes across at 48 km/h and returns at 48 km/h. Boat B goes across at 24 km/h, and its crew, realizing how far behind it is getting, returns at 72 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. A) By how much? B)What is the average velocity of the winning boat? 2)A race car moves such that its position...
The acceleration of a race car for the first few seconds of the race can be approximated by the a(t) = A + Bt linear formula, where t is the time measured in seconds and the values of the constants A and B are: A = 16.0 m/s2 and B = -2.00 m/s3. What is the speed of the car 2.30 s after it starts from rest? How much distance does the car cover during this 2.30 s time period?
I do not understand Part B.
