Answer 1

ANSWER = 192 m

$\huge\mathfrak\red{question}$

a boat moves from rest at constant acceleration of 3 m/s²

and takes 8 seconds to reach it . Find the distance travelled by the boat

$\huge\mathfrak\blue{Solution}$

acceleration , a = 3.0 m/s²

time taken , t = 8 second

given that it started from rest ,

initial velocity, u = 0

$\boxed{ \: a \: = \frac{v - u}{t} }$

$3 = \frac{v - 0}{8}$

$3 = \frac{v}{8}$

$v = 24ms {}^{ - 1}$

$\boxed{displacement = velocity \: \times \: time } \:$

$s = v \times t$

$s = 24 \times 8$

$s = 192 \: m$

Answer 2

Answer:

Given,

Boat acceleration, a=3ms‐²

Time, t=8sec

Apply kinematic equation of motion.

s=ut+1/2at²

s=0+1/2×3×8²=96m

Hence, boat travel 96m
