Homework Statement
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
Homework Equations
[itex]\phi[/itex]=BA
[itex]\epsilon[/itex]=-N[itex]\Delta\phi[/itex]/[itex]\Delta[/itex]t
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?
