Question

1) A ball is dropped from the Eiffel Tower (300 m), how long would it take for the ball to reach a velocity of 65 m/s? How far did the ball go in that time?

Answer 1

Answer:

Explanation:

If you drop a ball from

the top of a building it

gains speed as it falls.

• Every second, its

speed increases by

10 m/s.

• Also it does not fall

equal distances in

equal time intervals

• If the acceleration = 0 then the velocity is

constant. [remember that acceleration is

the rate of change of velocity]

• In this case the distance an object will

travel in a certain amount of time is given

by distance = velocity x time

• For example, if you drive at 60 mph for

one hour you go 60 mph x 1 hr = 60 mi.
