Question

a motorboat starting from rest on a lake acclerates in a straight line at a constant rate of 3m/s for 8 m/s how far doesthe boat travel during this time

Answer 1

u = 0

v = 8 m/s

t = ?

s= ?

a = 3

$v^{2} + u^{2} = 2as$

64 = 6s

s = 64/ 6 m

= 10.6 m

Answer 2

Answer:

96m

Explanation:

Given,

Boat acceleration=3m/s

Time, t=8s

Applying kinetic equation of motion

s=ut+1/2at^2

s=0+1/2×3×8^2 =96

Hence, boat travel 96m.
