Consult Multiple-Concept Example 5 in preparation for this problem. The velocity of a diver just before hitting the water is -10.5 m/s, where the minus sign indicates that her motion is directly downward. What is her displacement during the last 1.17 s of the dive?

Question

anonymous · Answer

Your using the equation velocity= displacement/time
and you want to get displacement by itself by multiplying time to BOTH sides.
by plugging in the numbers you'll get $$time(-10.5 m/s = displacement \div 1.17 s)$$
so 1.17s moves to the other side so the equation would just look like $$(-10.5 m/s)(1.17s)= -12.285$$

I have been trying to divide this entire time. I did not realize that if I move displacement over that I would change my division to multiplication. Also, the book is showing me all kinds of crazy stuff to do. Thank you for helping me out.
