Question

A truck accelerates from rest to a speed of 17 m/s in 9.1 s. If the tires have a radius of 33 cm, how many revolutions do the tires make during this time

Answer 1

u need to use formula as below
v=u+at
v^2=u^2+2as
circumferance=2*pi*r
revolution no.=s/2*pi*r

Answer 2

i got this question from the help i got when i last posted it.

Answer 3

ok

Answer 4

can you define your variables??

Answer 5

ya
v= final velocity
u= initial velocity
s=distance travelled
a=acceleration
r=radius of tyre
t= time

Answer 6

thanks I got it right this time.
