a race car accelerates uniformly from 18.5 m/s to 46.1m/s in 2.47 seconds determine the acceleration of the car and the distance traveled? given and answer |
| Answer» INITIAL velocityv=final velocitya=accelarationt=total TIME takens=DISTANCE travelledwe KNOW that,(v-u)/t=aso, (46.1-18.5)/2.47=a27.6/2.47=a=11.17m/s^2now, s(distance)=ut+1/2at^2=(18.5×2.47)+(1/2×2.47×2.47)=45.695+34.0735265=79.7685265=79.77m | |
