Answer:

Given :

Acceleration of boat = 3 m/s²

Time = 8 seconds

To Find :

The distance travelled by the boat during that time

Solution :

From second equation of motion ,

 \\  \star \: {\boxed{\sf{\purple{s = ut +  \dfrac{1}{2}a {t}^{2}  }}}} \\

Where ,

u is initial velocity

t is time

a is acceleration

s is distance travelled

We have ,

  • u = 0 [starting from rest]
  • t = 8 sec
  • a = 8 m/s²

Substituting the values in the equation ,

 \\   : \implies \sf \: s = (0)(8) +  \dfrac{1}{2} (3 )  {(8)}^{2}   \\  \\

 \\   : \implies \sf \: s =  \dfrac{1}{2} (3)(64) \\  \\

 \\   : \implies \sf \: s = 32 \times 3 \: m \\  \\

 \\   : \implies{\underline{\boxed{\pink{\mathfrak{s = 96 \: m}}}}} \:  \bigstar \\  \\

Hence ,

The distance travelled by the boat during that time is 96 m.
