I am still doing my lab and now I am stuck on this collision. Can anyone tell me if i did this right.
*U=initial velocity and V=final velocity
Mass 1 = Mass 2 = 0.541 kg
U(1)= 0.29 m/s [40 N of E]
U(2)= 0.29 m/s [35 N of W]
V(1) =0.26 m/s [36 N of W]
V(2) = 0.26 m/s [30 N of E]
Oh these values were measured they weren't given to me.
Ok here are my calculations.
Ekbefore=Ekafter
1/2m(1)U(1)^2 + 1/2m(2)U(2)^2 = 1/2m(1)V(1)^2 + 1/2m(2)V(1)^2
0.29^2 + 0.29^2 = 0.26^2 + 0.26^2
0.1682=0.1352
How would you find the percentage of error and what percentage would be reason to be off by.
Pbefore=Pafter
m(1)U(1) + m(2)U(2) = m(1)V(1) + m(2)V(2)
0.29[40 N of E] + 0.29[35 N of W] = 0.26[36 N of W] + 0.26[30 N of E]
X component of Pbefore.
0.29cos40 - 0.29cos35 = -0.0154
Y-component
0.29sin40 + 0.29sin35 = 0.353
Pbefore = square root (0.353^2 + 0.0154^2) = 0.353
Pafter x = -0.26cos36 + 0.26cos30 = 0.0148
Pafter y = 0.26sin36 + 0.26sin30 = 0.253
Pafter = square root (0.253^2 + 0.0148^2) = 0.253
Is that all right or am i doing something wrong.
