Estimate the order of magnitude of the length of a football field,
a. 10-1 m
c. 104 m
b. 102 m
d. 100 m

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.
