how much time does a car with an acceleration of 5m/s^2 take to go from 5m/s to 40m/s
change in v = a*t so t = v / a
The required increase in speed is 40-5m/s = 35m/s
Increasing speed at a=5m/s /s will take t = v / a (35m/s) / (5m/s /s) = 7s
change in v = a*t so t = v / a
The required increase in speed is 40-5m/s = 35m/s
Increasing speed at a=5m/s /s will take t = v / a (35m/s) / (5m/s /s) = 7s
