Question

The figure shows the graph of velocity versus
time for a particle going along the X-axis. Find (a) the acceleration (b) the distance travelled in 0 to 10 s and (c) the displacement in 0 to 10 s.​

Answer 1

Explanation:

$a) \: \: \: \: acceleration = \frac{v - u}{t} \\ \\ = \frac{8 - 2}{10} \\ \\ = 0.6 \: m {s}^{ - 2} \\ \\ b) \: \: \: \: distance = \frac{1}{2} \times (8 + 2) \times 10 \\ \\ = 5 \times 10 \\ \\ = 50 \: m \\ \\ c) \: \: \: displacement = distance = 50 \: m.$
