Find the speed of two objects if when they move uniformly towards each other, they get 4.0 metres closer each second and when they move uniformly in the same direction with original speeds, they ger 4.0 metres closer each 10 sec |

Answer» Solution :LET their speeds be `v_(1) and v_(2)` and let `v_(1) gt v_(2)` In first Case In SECOND Case: Relative velocity `v_(1)-v_(2)=(4)/(10)=0.4""....(2)` Solving eqns. (1) and (2) we get `v_(1)=2.2 m s^(-1), v_(2) 1.8m s^(-1)` |
