Homework Statement
Ball A is thrown vertically by speed 40 m/s. After 1 second, Ball B is thrown vertically also by speed 47.5 m/s.
What height from ground will they pass each other? ( g = 10m/s2 )
Homework Equations
s = vt + ½at2
t = v/g
v2 = v02 + 2as
The Attempt at a Solution
Time A to reach the max height is t = v/g = 40/10 = 4 s
I don't understand. Because there is plus of 1 sec for ball B.
