Question

A moterboat starting from rest on a lake accelerates in a straight line at a constant rate of 2 m/sec ² for 4 sec how far does the boat travel during this time ?​

Answer 1

Answer:

Do like this but change the values

Explanation:

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= o (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
