Question

A bike accelerates uniformly from rest to a speed of $7.10m/s$ over a distance of $35.4m$. Determine the acceleration of the bike. (in $m/s^2$)

• A. $0.712$
  
• B. $0.71$
  
• C. $0.7$
  
• D. $7.71$
  

Answer 1

The correct option is A $0.712$

Given, initial velocity, $u=0m/s$ and final velocity $v=7.10m/s$

Distance traveled $S=35.4m$

If $a$ be the acceleration.

Using formula $v^2-u^2=2aS$

$(7.10{)}^2-0^2=2a(35.4)$

$⟹$ $a=0.712m/s^2$
