Homework Statement
An object is released from rest in the gravitational field of the Earth. Air resistance is negligible. How far does the object move during the fourth second of its motion?
A. 15 m
B. 25 m
C. 35 m
D. 45 m
Homework Equations
v = u + at
s = ut + 1/2 at^2
v^2=u^+2as
s=(u+v)t/s
The Attempt at a Solution
u=0
a=10m/s^2
t=4
Now I am blocked... which equation should I use?
Thank you
