I have more I need help with also. I keep getting the wrong answers for these two.

1.

f=ma
f=qE

------
E=dV/ds <--- i think it's -dv/ds, idk been some time , but that doesn't matter much

For -dv/DX I get 1600sin3 +320(1.5) which is 706

I do qE =1E-6*706=ma

1E-6*706 over 5E-6 and it doesn't come out to the proper answer of 18.6 m/s^2 or at least what the key sheet says

what about -dv/dx(1.5) = 706

706(1E-6) = .5mv^2

.001412=5E-6kg v^2

282.4 = v^2

v = 16.8m/s

I might have copied the key down wrong with my dyslexia

hmm, idk then :/
