The cart's acceleration to the right after the mass is released is determined as 7.54 m/s².
<h3>
Acceleration of the cart</h3>
The acceleration of the cart is determined from the net force acting on the mass-cart system.
Upward force = Downward force
ma = mg
13a = 10(9.8)
13a = 98
a = 98/13
a = 7.54 m/s²
Thus, the cart's acceleration to the right after the mass is released is determined as 7.54 m/s².

The Electric field is E=23400 V/m.
What is electric potential ?
The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential). More specifically, it is the energy per unit charge for a test charge that is negligibly disruptive to the field under discussion.
The electric field of a spherical conductor is given by:

Here 'E' is the electric field and 'Q' is the electric charge.
therefore putting the values we get,
E=23400 V/m

You have to find interia using I=mr^2.
m=75+10
radius = 11
Then you have to substitute in first formula above to find the angular speed.
14020=(75+10)x v x 11
v= 14020/ (85x11) = 15m/s
To find linear speed, use V=wr.
Equation: V = 11*1.363 = 15m/s = 33.6mi/hr
Hope this helps! :)
