Didn't use algebra but Gary would be 3 and Karen would be 13 so in 2 years Gary would be 5 and Karen would be 15 and 5 x 3 = 15 so ya.
Answer:
6
Step-by-step explanation:
28 divided by 4 = 6
Force = mass x acceleration (F=ma)
When the parachutist reaches terminal velocity they are moving at a constant speed and no longer accelerating so acceleration (a) would be 0
so F would also be 0 since anything multiplied by 0 = 0
this would also mean that Fdrag must exactly balance Fg
so Fdrag would = -Fg, so Fdrag would be -850 N
