Question

A carpenter on the roof of a building accidentally drops herhammer. As the hammer falls it passes two windows of equal height,a) Is the increase in seed of the hammer as it drops past window 1greater than, less than or equal to the increase in speed as itdrops past window 2? b) Choose the best explanation from thefollowing:
I. The greater seed at window 2 results in a greater increase inspeed.
II. Constant acceleration means the hammer speeds up the sameamount for each window.
III. The hammer spends more time dropping past window 1.




Please explain with steps so I cant fully understand. Thank You! :)

Explanation / Answer

     Given that the initial velocity ofhammer is U = o ----------------------------------------------------------------------- (a) The final velocity of the hammer isV2 = U2 + 2gh                                                                 = 0 + 2gh      Hence the final velocity increaseswith distance          Then  hammer as it drops past window1 less than increase in speed as it drops past window2 (b)           The hammer spends more time dropping past window 1.
