A baseball has been thrown 0.15 kilometers into the air under normal earth gravity
(9.8 m/s2) If the baseball has 55 joules of potential energy, what is the mass of the
baseball?

Answer :

Lanuel

Answer:

M = 0.037kg

Explanation:

Given the following data

Height, h = 0.15 km to meters = 0.15*1000 = 150m

P.E = 55J

Acceleration due to gravity, g = 9.8m/s²

To find the mass

P.E = mgh

Substituting into the equation, we have

55 = m*9.8*150

55 = 1470*m

Mass, m = 55/1470

Mass, m = 0.037kg
