(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

assuming that friction is negligible and tthat electromagnetic forces are constant, (when they occur) calculate the speed of the cart at point 5w

this is part IV of a question, so in the other parts and in the given, i found out that:

mass of the cart=0.5kg

number of loops=150

hieght of the rampo=0.4m

height of the wire=0.1

width=0.2m

Resistance: 2.5 ohms

Magnetic field=1.2T

2. Relevant equations

[itex]\phi[/itex]=BA

[itex]\epsilon[/itex]=-N[itex]\Delta\phi[/itex]/[itex]\Delta[/itex]t

3. The attempt at a solution

The velocity of the cart at the bottom of the ramp is 2.8m/s

the Voltage of the cart as it enters the field is 50V

the current induced is 20A

The force of teh cart as it enters the field is 2.4N, making its acceleration 4.8m/s/s

Normal kinematics don't seem to work well, any tip?
