Question

A bicycle running on30m/s after increasing the speed is 45m/s in 15s find acceleration

Answer 1

Answer:

hi

i have attached the answer

the acceleration is 1m/s^2

hope it helps....

Answer 2

$\large \underline{ \underline{ \sf \: Solution : \: \: \: }}$

Given ,

$\star$Initial velocity (u) = 30 m/s

$\star$Final velocity (v) = 45 m/s

$\star$Time = 15 sec

We know that ,

$\large \sf\fbox{\fbox{Acceleration = \frac{v - u}{t} }}$

$\implies \sf Acceleration = \frac{45 - 30}{15} \\ \\ \implies \sf Acceleration = \frac{15}{15} \\ \\ \implies \sf Acceleration = 1 \: \: m/ {s}^{2}$

$\therefore$The required value of acceleration is 1 m/s²
