Suppose the tourist in question #1 instead thre the rock with an initial velocity of 8.0 m/s [up]. Determine the velocity and displacement of the rock at 4.0 s (Remember the initial velocity is down and must become a +8.0m/s)

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.

Because light travels in a straight line and casts a shadow, isaac newton hypothesized that light is

The necleus of an atom is made up of what subatomic particles?
