Question

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

Answer 1

Hey buddy! Here's your answer!

u = 0 m/s

t = 8 s

a = 3 m/s^2

s = ut + 1/2*a*t^2

  = 0 + 1/2*3*64

s = 96 m

Hope this helps! :)

Answer 2

a=v/ t

a= s/t/t

a= s/ t^2

3= s / 8^2

s= 64 ×3

s=192 m
