Uring a downhill bike race, one biker has a total mechanical energy of 8220 Joules. The biker is currently traveling at 12 m/s without having
pedaled, as he speeds down the hill (allowing gravity to do the work). The kinetic energy at this point in time is 5062 J. Calculate the original
(starting) height of the hill. (Round to the nearest tenth place)

c

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

answer: sorry i can't you.

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
