Ball at bottom of loop. 2.7 ms^-1 that was bloody hard
Momentum coin-1.6 ms^-1
6 marker on coin, resultant force =-km, use suvat, another bs question
6 marker muons, relativistic time dilation so half life and distance travelled increases
Flower field strength idek, but wasn’t radial
To prove collision was inelastic do 1/2 mv^2 before and after.
Mass was like 8.8 X 10 ^ something cant remember exactly
State the 2 conservation laws: I said Energy and momentum.
Use I=nAvQ with q=e and A=d x t, and rearranging for v then plug in F= bqv. Make it equal to Vhall X q/r then rearrange.
Units on either side of the derive equation gave me Nm/C.
E=V/d in this case as d was separation
D/a is the 1/t thing so
