Teaching NVS PGT 2024 Test Series Physics Motion in a Straight Line Kinematic equations for uniformly accelerated motion
A car accelerates from rest at a constant rate α for some time after which it decelerates at a constant rate β to come to rest. If the total time elapsed is t seconds, the total distance travelled is:
1
\(\frac{2\alpha \beta}{(\alpha+\beta)}t^2\)
2
\(\frac{\alpha \beta}{2(\alpha+\beta)}t^2\)
3
\(\frac{4\alpha \beta}{(\alpha+\beta)}t^2\)
4
\(\frac{\alpha \beta}{4(\alpha+\beta)}t^2\)
