Question

ball is thrown vertically upward with a speed of 120m/s. It's speed at midpoint of it's path is about ( g=10)

Answer 1

189.657 approximate 190m/sec , first you comment me that my answer is correct then I will edit the detailed answer,.

Answer 2

u=20m/s
g=a=10m/s
time=1

v=u+at
v=u+gt
v=120m/s+10m/s×1sec
v=120+10×1
v=120+10
v=130m/s
