Question

A small ball (ball 1) is released from rest; i.e. dropped, at the origin (0,0) and falls freely. At the same time another ball (ball 2) leaves the same position with an initial horizontal velocity of 3.10 m/s. Write your answers to THREE significant figures, where sig figs are required, and include units where none are given.

a)Calculate the time it takes ball 1 to fall 3.50 m.

b)What is the time it takes ball 2 to fall 3.50 m?


c)Calculate the horizontal distance ball 2 will move during this time.


d )Calculate the vertical component of the velocity of ball 1 after it has fallen 3.50 m.
(magnitude - Remember that the magnitude of a vector is always positive)

e)What is the vertical component of the velocity of ball 2 after it has fallen 3.50 m

f) What is velocity vector of ball 1 after it has fallen 3.50 m.
(magnitude)
