A force of 5 N produces an acceleration of8 m/s on a mass m, and an acceleration of24 m/s on a mass m2. Find the accelerationthat the same force would provide if boththe masses are tied together. |

Answer» Explanation: for first mass m1, F=5N. a= 8m/s² since F=ma =>5=m1X8 =>m=5/8kg for second mass m2, F=5N. a= 24m/s² m2= 5/24kg when both MASSES are TIED TOGETHER, that NEW mass will be m1+m2=5/8+5/24 =20/24=5/6kg F=5N. m=5/6kg F=ma =>5=5/6 X a => a=6m/s² |
