Homework Help: Projectile Motion: Height of hammer thrown downwards

  1. Feb 24, 2017 #1
    Hey Guys, I have attempted the question below and need someone to check my work, please.


    1. The problem statement, all variables and given/known data

    If the hammer was tossed downward at 4.6 m/s from a height of 9.5 m above ground level, how high would it be after 0.75 s?

    2. Relevant equations

    3. The attempt at a solution

    Your result turned out okay. However, you should avoid rounding intermediate values to the number of significant figures. Keep a few extra digits in intermediate values, and only round your results at the end. Otherwise, rounding/'truncation errors will creep into your significant figures by the end of the calculations.

    I'm changing your thread title to make it more descriptive of the problem being asked. Too-general thread titles, such as "Projectile motion" are not allowed as it is impossible to differentiate one such thread from another by thread title.
