Question

A boat in the river accelerates in a straight line starting from rest at a constant rate of $3{\text{m/s}}^2$ for $10\text{s}$. How far does the boat travel during this time ?

• A. $96\text{m}$
• B. $104\text{m}$
• C. $150\text{m}$
• D. $76\text{m}$

Answer 1

The correct option is C $150\text{m}$

We know that,

$S=ut+\frac{1}{2}a{t}^2$

$\Rightarrow S=0+\frac{1}{2}\times 3\times {10}^2=150\text{m}$
