Hey guys! New to the forum! :)
Anyways, so in Physics class my teacher gave us these three equations on Kinematics. He says that "pretty much everything can be done with these three", and here they are:
V(final)= V(0) + AT
V(final)^2= V(initial)^2 + 2A(ΔX)
and...
X(final) - X(initial)= V(initial)T + 1/2AT^2So V= velocity
A= Acceleration
T= Time
X= Distance So he makes us use these equations to do calculations and solve problems such as "Ball thrown up from ground at 23 m/s.. Where is it after 3.7 sec?" And, "Stone thrown down from high cliff at 12 m/s. How fast is it moving after 14 sec?"
I've been wanting to know how I determine which equation to use for each problem, and how to properly plug in the data. Also, I politely request that you solve the above problems I listed, preferably in a step-by-step manner. Thanks!
