Question

a ball thrown vertically upwards with a velociy of 15 ms calculate the maximum height reach by ball​

Answer 1

Answer:

➡️initial velocity ,u=15m/s

➡️at maximum height it reaches, it's velocity will be 0 m/s

➡️acceleration will be -g

according to the equation,

2as = v^2-u^2

we have,

s = (0-15×15)/2×-9.8

s= -225/-19.6

s = 2250/196

s = 1125/98 = 11.48
