Question

if i drive 50 mph and speed up steadily to 70mph over a 30 min period, how far will i have traveled during the 30 min period of acceleration?

Answer 1

First find acceleration
then use -
s = ut + (1/2)at^2

The above ^^ analysis assumes that you don't crash :P

Answer 2

i have been ttying but can't figure this problem out. i am getting so frustrated, i have an exam tomorrow and don't want to fail

Answer 3

Can you find acceleration ??

Answer 4

not really i am not good with math

Answer 5

a = (v-u)/t
where v = final velocity
u = initial velocity
t = time period

Answer 6

i've been doing speed=x time. i have been racking my brains. can't come up with an ans. according to my practice book, the ans is either 20 miles, 27.5 miles, 35 miles or 42.5 miles. i can't get any of these ans

Answer 7

Find acceleration first; then use the equation -
distance = u*t + (1/2)*a*t*t

Do one step at a time..

Answer 8

ok. i will try again but doubt it. thanks

Answer 9

i am stumped, but thanks anyway have a good niite
