Question

A motorboat starting from rest on a lake accelerates in a straight line at a constant rate of 5 m/s2 for 10 secs. How far does the boat travel during this time?​

Answer 1

ANSWER:

Initial velocity, u = 0

a = 5 m/s2

t= 10 secs

s= ut + 1/2 at^2

s= 0× 10 + 1/2 × 5 (10)^2

s= 0 + 1/2× 5 × 100

s= 500/2

s= 250 m
