Striking a fixed object at 60 mph is the same as falling from a story building: 9 10 12

121 ft

Step-by-step explanation:

60 MPH=(60×1760×3)÷(1×3600)=88 ft/

88²-0²=2×32×h

h=(88×88)÷(2×32)=121 ft

v^2-u^2=2gh

Explanation:

So 552 digits are used to number the pages of a book consecutively from page one. How many pages are there in the book?

1 to 9 = 9 digits

10 to 99 = 2*90 = 180 digits

So, 1 to 99 uses 189 digits.

552 - 189 = 363

3 digits per page = 363/3 = 121 pages starting at page 100.

Page 100 to 220 is 121 pages

220 pages in total

I hope this is logic is right - you might want a second opinion, too.
