Question

A car increases it's velocity from 2.0 m/s to 10m/s in 2.0 seconds. What is the car's acceleration?

Answer 1

Answer:

4m/s sq

Explanation:

apply v - u / t

10 - 2 / 2

8 / 2

= 4

Answer 2

$\mathfrak{ \red{given:-}} \\ \\ Initial \: Velocity \: u = 2.0 \: m/s,</p><p> \\ Final \: Velocity \: v = 10 \: m/s,</p><p> \\ Time \: taken \: t = 2 \: s.$

$\mathfrak { \blue{to \: find \: acceleration \: of \: car}} = \frac{v - u}{t}$

$\mathfrak { \red{ = > acceleration \: of \: car}} = \frac{v - u}{t} \\ \\ \mathfrak { \red{ = > acceleration \: of \: car}} = \frac{10 - 2}{2} \\ \\ \mathfrak { \red{ = > acceleration \: of \: car}} = \frac{8}{2} \\ \\ \mathfrak { \red{ = > acceleration \: of \: car}} = 4 \: m/{s}^{2} \\ \\ \mathfrak{ \: hence \: acceleration \: of \: car} = 4 \: m/{s}^{2} \\ \\ \\ \\ \mathfrak {\fbox{ \red{i \: hope \: it \: helps \: you.}} }$
