Name:    Physics -- Acceleration Word Problems                            A = FV - OV / T (Note:  The problems may look familiar, but the numbers are different!)

(Note:  Print this test out on your printer.  Use the included solution boxes to work out your answer.
When you have the answers, come back to the web page and input your answers using the guidelines
listed below.  This test accepts answers in the format of
A = 3 m/sec/sec     (or)     A=3m/sec/sec
--- in other words, your answers must either have a space after the missing variable, a space after the
equals mark, and a space after the number OR no spaces!)

7.

A miner drops his rock hammer down a mine shaft by mistake.
If it takes the hammer 18.5 seconds to hit the bottom of the shaft,
what is the
FINAL VELOCITY of the hammer at impact?
(Hint:  Remember that on earth acceleration due to gravity is 9.8 m/sec/sec.)

9.

The space shuttle blasts off from Florida at an acceleration rate of 15 km/hr/sec
and reaches a final velocity of 17,118 km/hr.
How much
TIME did it take to reach this final velocity?
 Data Type of Problem& Formula Equation Solution Answer Check Step

10.

A rock is dropped from a building and when it finally hits the ground reaches
a final velocity of 95 meters/second. If it fell at the gravity constant rate of 9.8 m/sec/sec.
How much
TIME  did it take to hit the ground?
(Note:  Remember that the rock starts at a rest, which means its OV is 0 m/sec.).
