Graduate from college ! I’m a freshman at SDSU :) two things would be to stay dedicated to my studies and not give into distractions!!!
First determine the net force. Let's say the downwards force is negative and the upwards force is positive.
Since the forces act in opposite directions, the net force would be:
400N - 600N = -200N
Since I said negative is downwards, this translates to the net force being 200N downwards.
Force = mass*acceleration
200N = 60kg * acceleration
acceleration = 3.33 m/s^2
Taking g = 10m/s,
Initial velocity (u) = 0 m/s
Time (t) = 0.5s
d = ut + 1/2 (gt²)
d = 0 + 1/2 (10x0.5²)
d = 1/2 (5/2)
d = 5/4
d = 1.25m
Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
