Question

A car travelling initially at a speed of 10 m/s is accelerated so that the speed
increases to 110 m/s in 5s. The acceleration of the car will be

Answer 1

Answer:

110-10/5=100/5=20m/s^2

Answer 2

$\bold{ \underline{ \huge \purple{{Answer:-}}}}$

initial speed (i.s) = 10 m/s

final speed (f.s) = 110 m/s

∴ change in speed (Δ v) = f.s - i.s = 110 m/s - 10 m/s = 100 m/s

time taken (t) = 5 s

$\bold{∴ acceleration = \frac{Δ v}{t} } \\ \bold{ = \frac{100}{5} = \underline{20 \: m/s {}^{2} }}$
