Acceleration ?
Asked by omprakasharya123 | 22 Aug, 2010, 05:49: PM
answered-by-expert Expert Answer
1. Acceleration = (Final velocity - Initial velocity)/time = (36 km/hr - 0 km/hr)/ (10/60 hr) = 216 km/hr2
2. Time = (Final Velocity - Initial Velocity)/(Deceleration)
            = (0 - 0.5 m/s)/(-0.5m/s2) = 1 sec.
