<span>Vi=8.55m/s
</span><span><span>Ff</span>=<span>Uk</span>mg=0.45m(9.8m/<span>s2</span>)</span>
Calculate the acceleration (which will be negative since it's due to the force of friction):
<span>
a=<span>Fm</span></span><span>a=<span><span>(0.45)(9.8m/<span>s2</span>)m</span>m</span></span><span>a=4.41m/<span>s2</span></span>
Time to stop:<span>t=<span><span>8.55m/s</span><span>4.41m/<span>s2</span></span></span>=1.94s</span>
Now see how far they go in 1.94s with an acceleration of -4.41m/s^2:<span>x=<span>V0</span>t+<span>12</span>a<span>t2</span></span><span>x=(8.55m/s)(1.94s)+<span>12</span>(−4.41m/<span>s2</span>)(1.94s<span>)2</span>=8.29m</span>
Answer: X is NOT equal to -2
Step-by-step explanation:
Because 36 divided by 18 is 2. not negative 2.
you can copy and paste that if you need to :)
AB would equal 3.57 or 3.6 rounded as your directions ask because the sides are supposed to be proportional. When you do 21/5, you get 4.2. Then, you can just do 15/4.2 and get 3.57.
Answer: 2 2/3
Step-by-step explanation:
we have to turn this into a improper fractions first (so its something like a bobble-head)
(2 2/5) 5 x 2 = 10 + 2 = 11/5
(3 1/4) 3 x 4 = 12 + 1 = 13/4
Then add those two.
11/5 + 13/4
11 + 13 = 24
5 + 4 = 9
so now its time to put it in simplest form 8/3
Now 8 divided by 3...BUT WAIT...3 can't go into 8
Now we turn it into a Mixed Number 2 2/3
The answer is a^mn, hope this helped
