A 5.0 kg sphere initially at rest is allowed to fall toward the earth for a time of 5.0 s (g = 10 m/s? ). Its velocity at the end of this time is: A) 10 m/s down
B) 40 m/s down
C) 20 m/s down
D) 50 m/s down
E) 30 m/s down

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
