Question

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 3.0 m s for 5.0 s. How far does the boat travel during this time?​

Answer 1

37.5

Step-by-step explanation:

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

Acceleration of the boat = 3 ms^-2

Time period = 5s

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

= 0 + 1/2(3)(5)^2

= 37.5 m
