Question

motorboat startin from the rest of the lake accelerates in a straight line at a constant raye 3.0m/s² for 8 seconds. How Far Does The Boat Travel During This Time.
​

Answer 1

Answer:

We know the equation of motion.

Distance, s = ut + (1/2)at2 —————-(i)

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

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

= 1/2 (3) (64)

= 3(32)

= 96

Therefore, the distance travel by motorboat = 96 m

Answer 2

Answer:

Given :-

motorboat startin from the rest of the lake accelerates in a straight line at a constant raye 3.0m/s² for 8 seconds

To Find :-

Distance covered

Solution :-

As it starts from rest so, it's velocity will be 0 m/s

We know that

s = ut + ½at²

s = 0 × 8 + ½ × 3 × (8)²

s = 0 + ½ × 3 × 64

s = 0 + 3 × 32

s = 96 m
