d= 66 ft/s2 over 70.84 ft so we multiply the numerator by the denominator to get the answer then move the decimal over twice and then put the answer in feet. d= 61ft. So do you have any questions or anything?
Hello there, miss jacoby ,come before you're late
So Mr. todd I really need help understanding this braking distance stuff it's really hard .
okay mr todd i'll see you there
Of course I can Miss. Jacoby! So miss jacoby you need to come to tutoring after school today to get help
Okay so miss jacoby so first you'll need to write down the formula since our fps is already given.
Next you'll need to write down the formula and the given information. d= (66fts2) Now write the given, d=66 fts , G=0.30, g= the constant which will always be 32.2, and f=0.8. Next substitute the variables with the given. 2(32.3/s2) times (0.8+0.30). What I did here was plug them in now we gotta solve it. So you multiply 32.2 by 2 which will always be 64.4 next you add 0.8 and 0.30 which is known as f and G then add that answer to 1.1.
