Q
Provide the kinematic equation used when ACCELERATION is unknown; explain the different values of the equation
A
v aver. t = ((Vo + Vf)/2)t
t= time
Vo = initial velocity
Vf = final velocity

Q
Remember the steps needed before you start.
A 100g object has a speed of 3cm/s at point A and a kinetic energy of 7.5J at point B.
a) what is its kinetic energy at point A?
b) its speed at point B
c) the total work done on the particle as it moves from A to B?
SI Units, identify what you know and dont know, answer, apply theory, un
