Answer 2

★ Given:-      

• ➝ Initial velocity = 0 m/s
• ➝ Final velocity = 6 m/s
• ➝ Time = 3 sec

★ To find:-      

• ➠ Acceleration of the motorcyclist.

★ Solution:-        

Here, we have an initial velocity is 0 m/s, the final velocity is 6 m/s and the time is 3 sec.

So, to find out the acceleration of the motorcyclist we will use the acceleration formula.

• $\large\boxed{\tt{Acceleration\:=\:\dfrac{Final\:velocity\:-\:Initial\:velocity}{Time taken}}}$

♡ On applying the formula ♡

$\qquad\tt{:\implies\:Acceleration\:=\:\dfrac{Final\:velocity\:-\:Initial\:velocity}{Time taken}}$

$\qquad\tt{:\implies\:Acceleration\:=\:\dfrac{(6\:-\:0)}{3}}$

$\qquad\tt{:\implies\:Acceleration\:=\:\dfrac{6}{3}}$

$\qquad\tt{:\implies\:Acceleration\:=\:2\:m/s^{2}}$

$. ° . \:\underline{\bf{The\: acceleration\: of\: the\: motorcyclist\: is\: 2\: m/s^{2}\:.}}$
