JEE MainPhysicsMotion in A Straight LineMCQ+4 / −1
A car accelerates from rest at a constant rate α\alphaα for some time after which it decelerates at a constant rate β\betaβ to come to rest. If the total time elapsed is t seconds, the total distance travelled is :
  1. A
    4αβ(α+β)t2{{4\alpha \beta } \over {(\alpha + \beta )}}{t^2}(α+β)4αβ​t2
  2. B
    2αβ(α+β)t2{{2\alpha \beta } \over {(\alpha + \beta )}}{t^2}(α+β)2αβ​t2
  3. C
