A Pepsi bottle is dropped (released) from a height of 60.0 m. How fast is it going (m/s) when it still has 2.0 s left in its fall?

An object is thrown straight up from ground level with a speed of 40 m/s. If g = 10 m/s2 its distance above ground level 2.0 second later is:

In the figure, a stone is projected at a cliff of height h with an initial speed of 43.0 m/s directed at an angle θ0 = 61.0 ° above the horizontal. The stone strikes at A, 5.18 s after launching. The height h of the cliff is
