Answer:
FALSE!!!
Explanation:
Business letters are formal and normally given to someone of higher importance.
Answer:
p=1
Explanation:
Well me know that v=m/s
and that a=m/s^2
so

Note: We don't take into account 2 because it's a scalar, it doesn't have units so it doesn't add anything to the equation.
10 x 4^2 = 160 / 8..
V = 20m/s...
...x 8 = 100 miles,meters, metric what ever m stands for after 8 seconds.
This is my guess since the problem says 4m/s^2
V= distance/ ST (traveled/used)
Answer:
a) 245 N
b) 392 J
c) 196 W
Explanation:
a) Force needed to lift the 25 kg object is the same as the weight of the object:

b) Work is the force exerted times the distance moved:

c) The power exerted is the quotient of the work done over the amount of time it took to move the object:
First, let's convert the initial angular speed from rpm (rev/min) into rad/s, keeping in mind that

and 1 min=60 s:

Now we can find the angular acceleration of the lp, keeping in mind that the final speed is zero:

and the acceleration is negative because the LP is decelerating.
Now we can find the angle covered by the LP from the beginning to the end of its motion:


And finally, we can convert it into number of revolutions:
