<span>The car would have traveled exactly one-half of the circumference of the track, since it would have gone from one extreme point to its opposite extreme point. This would be equal to (3.5 / 2), or 1.75 km. The northernmost point would be 1.75km away from the southernmost point.</span>
F = normal force by each board on each side
W = weight of the board in between acting in down direction = 95.5 N
f = frictional force in upward direction by each board
= coefficient of friction = 0.663
Using equilibrium of force in Upward direction
f + f = W
f = W/2
f = 95.5/2 = 47.75 N
frictional force is given as
f = F
47.75 = (0.663) F
F = 72.02 N
39.2 m/s
Since 9.8 is the acceleration of gravity times 4 gives you 39.2
The answer would be conformity. This is a kind
of social influence concerning a change in belief or conduct so one can fit in
with a group. This alteration is in reply to real (physical occurrence of
others) or fictional (pressure of social norms / prospects) group pressure.
Answer:
Explanation:
The formula for KE is
and we fill in to solve for KE:
I used 2 significant digits in the velocity because 1 isn't accurate enough. Therefore, my answer will be rounded to 2 sig fig's:
KE = 340 J (rounded from 343). And we do the exact same thing in #2:
(Used 2sig fig's for both the mass and the velocity) to get
KE = 63 J (rounded from 62.5)
