A cat pushes a ball from a 7.00 m high window, giving it a horizontal velocity of 0.20 m/s. how far from the base of the building does the ball land? (assume no air resistance and that ay = g = 9.81 m/s2.)

Sampson · Answer 1

Formulas are:

h = g t² / 2

x = v x * t

7 m = 9.81 m/s² * t² / 2

t² = 14 : 9.81

t² = 1.427

t = √1.427 = 1.19 s

x = 0.2 m/s * 1.19 s

x = 0.24 m

Answer: The ball lands 0.24 m from the base of the building.
