A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s–2 for 8.0 s. How far does the boat travel during this time?

Answer

Solution

Given, initial velocity of the boat = 0 m/s

Acceleration of the boat = 3 ms-2

Time period = 8s

As per the second motion equation, s = ut + 1/2 at2

Therefore, the total distance travelled by boat in 8 seconds = 0 + 1/2 (3)(8)2

= 96 meters

Therefore, the motorboat travels a distance of 96 meters in a time frame of 8 seconds.
