a) after 1 s the vertical velocity is 2 m/s
... so the average velocity is 7 m/s for the 1st sec
b) similar to a)
... the object reaches its peak after 1.2 s
... the average velocity is 6 m/s
c) time up equals time down
... 1.2 + 1.2
... so the average velocity is 7 m/s for the 1st sec
b) similar to a)
... the object reaches its peak after 1.2 s
... the average velocity is 6 m/s
c) time up equals time down
... 1.2 + 1.2
