Question

A car travels a velocity 10m/s and accelerated at 5m/ssqare. Calculate the final velocity. When it has travelled 30m

Answer 1

Answer:

Here is your answer buddy

Answer 2

U = 10 m/s

S = 30 m

A = ${5}^{2}$

V = ?

$\textsf{Using\:3rd\:equation\:of\:motion-}$

${v}^{2} = {u}^{2} + 2as \\ {v}^{2} = {10}^{2} + 2 \times 5 \times 30 \\ {v}^{2} = 100 + 300 \\ v = \sqrt{400} \\ v = {20}ms^{1}$

Therefore, when it has travel 30 m the final velocity will be 20 m/s.
