Acceleration of train when it is moving steadily from 4.0ms^-1 to 20ms^-1 in 100s is A)1ms^-2 B)2ms^-2 C)0.16ms^-2 D)3ms^-2

Question

Quizplus · Accepted Answer

Acceleration is calculated using the formula $a = \frac{\Delta v}{\Delta t}$, where $\Delta v$ is the change in velocity and $\Delta t$ is the change in time. Here, $\Delta v = 20ms^{-1} - 4ms^{-1} = 16ms^{-1}$ and $\Delta t = 100s$, so $a = \frac{16ms^{-1}}{100s} = 0.16ms^{-2}$.
