Question: A generator has 810 turns of wire wound with coils having a diameter of 0.310 m. The coils are put in a magnetic field of 0.050 T and produce a maximum emf of 140 V.
Part A: How fast is this generator rotating (in revolutions per minute)?
I need help to find how fast this generator rotating.

A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 400 grams (0.4 kg), at ends of a very low mass rod of length d = .6 m. The barbell spins clockwise with angular speed 20 radians/s.
A ball is thrown vertically upward by an initial speed of 11 m/s. One second later, a stone is thrown vertically upward with an initial speed of 25 m/s. Discover the time it takes the stone to catch up with the ball.
