Solve the below given problem:
 
A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of for \(5\ ms^{-2}\) for \(7\ s\).

How far does the boat travel during this time?
 
From the Equation of motion, We know that,
 
s=i×i+ii×i×ii
  
Travelled distance \(=\)  \(m\) 
 
[Note: Enter your answer with two decimal digits.]
