100 points easy physics A feather (mass = 0.1kg) and a bowling ball (4.5kg) will both fall at the SAME rate on Earth (g=9.8m/s2) if there is no air resistance. How much force does each item have if it is falling due to the acceleration of gravity?

use,

F = mg

For feather,

F = 0.1*9.8

F = 0.98N

For bowling bowl,

F = 4.5*9.8

F = 44.1N

Therefore the forces for the feather and the bowling bowl are 0.98N and 44.1N respectively.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
