I know what it looks like, I'm wondering "why"

Why does one "dips" down and the other rotates?

bump... no one knows?

Homework Statement suppose a bar magnet is brought near a magnetic needle in a way that does not disturb the latter's position in the magnetic meridian. What can be said concerning the direction of the field due to the magnet? 2. Would reversing the position of the magnet has any effects on...

What is the relationship between the mass and velocity of a whirling object? base of graph relationship What is the relationship between the radius of revolution and the velocity of a whirling object? What is the relationship between the velocity of a whirling object and the centripetal...

Je suis allé en France J'étais à la banque quand J'avais peur des chiens

bottom of swing velocity = 3.96m/s(if I did right) (3.96)(.2)=.2(x)+.4(y) x y are the velocities, not sure how to do next now.

Homework Statement A 0.200-kg mass is attached of a 0.800 m length string to form a pendulum. The pendulum is released from a horizontal position. At the bottom of its swing, it collides elastically with a 0.400-kg mass which is at rest on a horizontal, frictionless v surface. Find the...

the acceleration should be gravity? so 9.8m/s^2 but I don't know what's the accelerated motion formula. umm. I took square root of (9.8x44x2) and got 29.36s but that's not right, the answer my teacher gave was 2.98s... can't figure out what I did wrong.

Homework Statement An 80kg diver falls from a board into water 44m below the water. A)I found the potential energy of the diver on the board is 34496 B)kinetic energy as he stirkes the water=34496 C)I can figure out "how long does it take the diver to strike the water" Homework...
