Question

The average velocity of an object if travels 10 m in3 sec further 15 min 5 sec (1) 6,25ms 0,625 ms 62,5 ms 625ms

Answer 1

To find the average velocity we have to add the total displacement and divide it by the total time. In the first part of the journey, the object covers 10m in 3 seconds. In the second part of the journey, the object covers 15m in 5 seconds. The total  displacement in this journey is 25m. The total time is 8 seconds.

The average velocity $v$ of an object is the total displacement $d$ and total tile $t$is computed as follows,

$v=\frac{d}{t} =\frac{25}{8}=3.125m/s$

The average velocity of the object is 3.125m/s
