A construction worker falls 5 meters to the ground. a) How long does the fall take?
b) How fast is he going when he hits the floor (speed & acceleration)?​

the answer is d

explanation:

dan realized that his goal of going to an ivy league school if only he works hard which means basically this   to become completely aware of (something) as a fact; understand without a doubt to make (something desired or anticipated) occur to give real, definite or physical form to a plan, dream, or goal to earn (money or a profit) from a deal

hi there!

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