Question #a2118

Answer 1

See the answer below...

Explanation:

ACCELERATION:- change of velocity in a certain time...

If initial and final velocity are `color(red)(u` and `color(red)(v` respectively by time `color(red)(t` then the acceleration `(v-u)/t`unit.

Here acceleration is `color(darkred)((48.2-18.2)/2.45=12.25ms^-2`

Another formula to determine the distance(S) traveled is
`color(red)((v^2-u^2)/(2a)=s` where a is acceleration...

The distance is `color(red)((48.2^2-18.2^2)/(2xx12.25)=81.34m`
