I did something wrong here (again),
m2 is the mass of the falling weight
m1 is the mass of the cart (+ the mass of the ball on t=x)
it should be:
F=m*a --> m2*g = 0.5*9.81= 4.9N
Fres = m*a ---> 4.9N = (m2+m1)*a1 --->
4.9-m2 = m1*a1 --->
(4.9-m2)/a1= m1(t=x)
Fres = m*a ---> 4.9N =...
I see, so:
4.9 = (m1+m2)*1.8 = 0.9m1 --> 4.9/0.9= 5.4kg
and
4.9 = (m1+m2)*3.2 = 1.6m1 --> 4.9/1.6= 3kg
5.4-3 = 1.4kg = the mass of the ball
Is this the right way the solve this problem?
I want to say thank you for your support, I figured out how to do it (or at least how I think the problem is solved):
m1 = xkg
m2 = 0.5kg
a1 = 1.8m/s2
a2 = 3.2m/22
So the amount of force from the falling weight is 0.5x9.81=4.9N
F=m1 *a ---> 4.9 = x*1.8 ---> 4.9/1.8=2.7kg (before launch of...
Okay, so I now know the mass of the falling weight is 0.5kg and it falls at an acceleration rate of 1.8m/s2 before ejecting the ball, and at an acceleration rate of 3.2m/s2 after the ball is ejected. How can I calculate the mass of the ball with this information?
Homework Statement
I would like to know how I calculate mass of a ball based on a video. I can measure the speed of the ball at any point using Coach 3 (computer program). I know g=9.81m/s2 for the rest i don't know anything. I would like to know the way to calculate the mass of the ball in...
