A weighting 9800 N is moving at 25 m/s. If the frictional forceacting on it is 2000 N.how fast the car moving when it has travelled 60 m |

Answer» taking g = 9.8 m/s/s: mass of car = w / g = 9800 / 9.8 = 1,000 kg Negative acceleration of car = F / m = 2000 / 1000 = - 2 m/s/s Find V(f) USING kinematic equation: 2 a d = V(f)^2 - V(i)^2 → V(f) = 19.62 m/sExplanation: |
