Answer 1

Answer #1

The equation for free fall motion:

starting from rest:

the minus sign indicates that this displacement is downward.

So the ball has fallen 4.9 m

Answer C.

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 2.70 m/s. Calculate the time it takes ball 1 to fall 3.50 m. What is the time it takes ball 2 to fall 3.50 m? Calculate the horizontal distance ball 2 will move during this time. Calculate the vertical component of the velocity of...
