A student swings a 0.5kg rubber ball attached to a string over her head in a horizontal, circular path. The string is 1.5 meters long and in 60 seconds the ball makes 120 complete circles.

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?
