Question

A motorboat starting from rest on a lake
accelerates in a straight line at a constant rate
of 6 m/s2for 10 s. How far does the boat travel
during this time?
Select one:
A. 1200m
B. 100m
C. 600m
D. 300m​

Answer 1

We know the equation of motion

Distance, s = ut + (1/2)at2 —————-(i)

Substituting the given and known values in equation (i) we get,

s= 0 (8) + 1/2 (3) (8)2

= 1/2 (3) (64) { 82 = 8 X 8=64}

= 3(32)

= 96

Therefore, The distance travel by motorboat = 96 m
