2. a 5.2 x 10 kg car accelerates from rest under the
actions of two forces. one is a forward force of 3600
n provided by traction between the wheels and the
road. the other is 3350 n resistive force due to
various frictional forces. determine how far the car!
must travel for its speed to reach 7 m/s.

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
