What is the maximum lifting height of a 100 g body thrown vertically upwards at a speed of 15 m / s?

univerkov | November 17, 2020 | education

V = 15m / s
g = 10 m / s ^ 2
sin (90) = 1

Hmax = (V ^ 2 * sin ^ 2 (90)): 2g
Hmax = (225 * 1): 2 * 10 = 225: 20 = 11.25 m

OR
m = 100g = 0.1kg

Epo = 0
Ep = mgh
Eko = mv ^ 2/2
Ek = 0
mgh = mv ^ 2/2
h = mv ^ 2 / 2mg = v ^ 2 / 2g = 225/20 = 11.25m
