Question

An object which is vertically projected or falls from the sky has a velocity of 'v' and is given by: v = -32t + vo, where 'v' is the velocity in feet/sec, 't' is the time in seconds, and 'vo' is the initial velocity in feet per second. If the initial velocity is 300 feet/sec, and the velocity v is in the range of 44 < v < 76, find the time interval t.

Answer 1

what we're given ?
what we're asked to find out ?

Answer 2

v = -32t + vo is given

Answer 3

initial velocity is 300 feet/sec

Answer 4

yes, so plug that in

Answer 5

the time interval t.

Answer 6

v = -32t + 300

Answer 7

divide?

Answer 8

44 < v < 76

so

44 < -32t + 300 < 76

Answer 9

first subtract 300 through out

Answer 10

44 < -32t + 300 < 76
-300 - 300 -300

Answer 11

ok so the answer would be (7,8)?

Answer 12

Yep !

Answer 13

ok :) good getting it

Answer 14

I can see that you're a fast learner :) good job, keep it up !!
