Question
A car was stopped at a red light. When the light turns green, the car reaches a speed of 41 miles per hour in 1 seconds. What is the acceleration, to 1 decimal place?
Answers
Reiny
v = at + k
when t = 0 , v = 0, so k = 0147
when t = 1 sec = 1/3600 hr, v = 41mph
41 = a/3600
a = 147600 mi/hr^2
You did not specify what units you want
so I leave it up to you to change to the appropriate units
