Question

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 ms^
−2 for 8 s. How far does the boat travel during this time?

Answer 1

Answer:

Given, initial velocity of boat is: u=0

Acceleration is: a=3 ms^2

Time is: t=8 s

Using second equation of motion:

s=ut+  1/2at^2

s=0×8+  1/2×3×8^2  =96 m.
