Two particles P and Q move towards each other along a straight line MN 51 meters along P starts from M with a velocity 5m/s and a constant acceleration of 1m/s^2 Q starts from N at the same time with velocity 6m/s and a constant acceleration of 3m/s^2. Find the time the particles are 30 meters apart |

Answer» assuming TOTAL TIME is 2tfor P, at half timev=X.t,S1=21Xt2at full time S2=Xt.t+212Xt2=2Xt2total DISTANCE covered by P is S1+S2=2.5Xt2for particle Q, at half timev=2Xt,S1=212Xt2=Xt2at full time S2=2Xt.t+21Xt2=2.5Xt2total distance covered by Q is S1+S2=3.5Xt2so distance covered by Q is more then P.Explanation:plzz mark me as brainliastand plzz follow me.. |
