Problema Solution

a ball is thrown vertically upward from the top of the building 40m high with an innitial velocity of 25m/s. What is the total time that the ball is in the air?

Answer provided by our tutors

The total time is t

So the equation is

-40 = 25t - 0.5*9.8t^2

So

t = 6.38s

So the total time in the air is 6.38 seconds
