A body starts moving with uniform accelaration alpha for some time and retards uniformly (-beta)to come to rest. Let the total time be t. Then find Vmaximum and the distance travelled please answer this question correctly! I have tried this many times I didn't get it please answer this question!!! |

Answer» Let initial distance traveled by the car is s 1 , in time t 1 , and velocity is v 1 thens 1 = 21 αt 12 v 1 =αt 1 v 12 =2αs 1 let remaining distance traveled by the car is s 2 , in time t 2 , and velocity is v 2 thenNow, u 2 =v 1 So, s 2 =v 1 t 2 − 21 βt 22 v 2 =0=αt 1 −βt 2 ⇒ t 2 t 1 = αβ t 1 +t 2 =t⇒t 2 ( αβ +1)=t⇒t 2 = β+ααt So, t 1 =( β+αβt )Clearly MAXIMUM velocity attained is v 1 , sov 1 =αt 1 =( β+ααβt )Explanation:Hope it would help you and please MARK it as brainliest and please FOLLOW me. |
