A ball is dropped from a certain height and it reached the ground with a speed of 60 m/s. use acceleration due to gravity g = 10m/s2 and ignore the air resistance to determine the following:

. How long does the ball take to reach the ground?

. The height from which the ball was dropped

. Find the time needed for the ball to cover half(1/2) of the total height

. At what height from the ground, the ball will be after half the total time.

Student1 is standing at a certain height h(m) where student2 is at twice as high as the other. Each drops a ball at the same time. If the first ball strikes the ground at time t1 (Sec), (Disregard air resistance.)

Write the equation of t1 in terms of h

Write the equation of t2 in terms of h

How long does it take the second ball to reach the ground compared to t1
