A tow rope used to pull the car of mass 700kg will break if the tension exceeds 1500N.1. Calculate the maximum acceleration with which the car can be pulled through a level road 2. Calculate the minimum time required to bring the car to work station 500m away from the break point |

Answer» 1. T = ma 1500= 700 × a a = \(\frac{1500}{700}\) = 2.14 m/s . 2. S = ut + 1/2 at2 500= 0 + 1/2 × (2.14) × t2 t = \(\sqrt{\frac{2 \times 500}{2.14}}\) = 21.61sec. |
