3. A clown rides a small car at a speed of
15 km/h along a circular path with a
radius of 3.5 m. What is the
magnitude of the centripetal force on a
0.18-kg ball held by the clown?

Find the magnetic field a distance r from the center of a long wire that has radius a and carries a uniform current per unit area j in the positive z direction.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
