A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s-² for 8.0 s. How far does the boat travel during this time?

$\huge\sf\pink{Answer}$

Given -

Initial Velocity -

u = 0

Acceleration -

$a = 3.0 ms^{-2}$

Time taken-

t = 8 secs

Then,

$\bold\red{Using\: Equation\:of\: Motion}$

Distance travelled by the Boat --

$\boxed{s = ut + \frac{1}{2}at^{2}}$

$= 0× 8 +\frac{1}{2}×3×8^{2}$

$\bold\green{= 96\:Metres}$

Answer 2

Answer:

good morning

➧ u ➾ 0 m/s

➧ a ➾ 30 m/s²

➧ t ➾ 8 sec

❱S ➾ ut + ½ at²

S ➾ 0 × 8 + ½ × 3 × (8)²

S ➾ ½ × 3 × 64   ➾ 96 m ...✔_________               Thanks...✊
