x=x
_{0}
+v
_{0}
t+1/2at
^{2 }
Where x = distance (meters), v = velocity(meters/sec), a = acceleration(meters/sec/sec or meters/sec
^{2}
), and t = time(sec).
What is the formula for "frictional force"?
Where (mu) is the frictional coefficient and Fn is the normal force.
Formula for velocity?
v = d / t
Formula(s) for distance?
d = vt
d = v
_{avg}
t
d = v
_{initial }
t + 1/2 a t
^{2}
d = 1/2 a t
^{2 }
<--when at rest
Formula for velocity when no time avail?
v
_{final}
^{2 }
= v
_{initial}
^{2 }
+ 2 a d

v
_{yinitial }
= v sin (theta)
v
_{x}
= v cos (theta)
