Asked by Hauwart

A ball is thrown vertically up and from the ground with a velocity of 20ms. Calculate:
a-The maximum length reached.
b-The time to reach the maximum height.
c-The time to reach the ground again after the ball is thrown up.
d-The velocity reached halfway to the maximum height.
Assure g=10ms.

g does NOT equal 10 ms. Is that supposed to be milliseconds?

20 ms is also not a velocity

Perhaps they want you to USE g = 10 m/s^2.

Not only are you showing no work, you are not even copying the problem correctly.
