Given,
Acceleration(a) = 3 m/s²
Time (t) = 8 seconds
Initial velcoity (u) = 0 m/s
Final velocity (v) = 0 + 3 x 8
= 24 m/s
We know,
s = ut + 1/2 at²
s = 0 x 8 + 1/ 2 x 3 x 8 x 8
s = 0 + 32 * 3
s = 96
∴ Boat travelled = 96 m

➧ 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 ...✔
