5. A ball experiences a change in momentum of 24 kg-m/s. a. What is the impulse acting on the ball?
b. If the time of interaction is 0.15 s, what is the magni-
tude of the average force acting on the ball?

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

Which fators influence ocean currents

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
