a)What is the total energy in the system?
Only energy acting on the system assuming the track is level and there is no potential energy of the carts, is the potential energy of the spring.
Comes out to 7.8125 using the potential energy of a spring equation.
b) What are their velocities if the...
Thanks for the reply, my next question on the HW is
Air resistance takes 37 J of energy out of the ball, slowing it down while as it is moves between the pitcher and the catcher. What is the velocity of the ball just before it hits the catchers glove?
He gives us 0 info on the catcher, is this...
I've gone about getting the arclength S = 1.103m
The formula for average force is F = m * (Vf – Vi) / t
I know the mass and the initial velocity, but I don't know where arclength comes into play. I'm assuming Vf and T is referring to the moment that the ball leaves the pitchers hand, but I...
