Find the accelartion:

1 answer:

6 0

A. Man runs (> 2.2 m/s is running) uphill at 6 m/s (???) and decelerates to walking at 2.0 m/s near the top, all in 5 minutes, assuming he ran in a straight line.

Acceleration is (final velocity-initial velocity (m/s) )/time (s)
=(2-6)/(5*60)=-4/300= -0.0133 m/s^2

B. Car goes east for 300 km in 45 min.
Velocity
=300*1000 m / (45*60) s due east
=300000/2700 m/s due east
=111.1 m/s due east
(is it an airplane? A cesna cruises at 63 m/s (226 km/h) )

What is the factors of 250,45,30?

Blizzard [7]

250, 45, and 30 have a common factor of 5 because that's the only number besides 1 that all three number are divisible by. 375, 66, and 33 are all divisible by 3 so the common factor of these numbers is 3. finally, 76, 21, and 14 have no common factors other than 1; but 76 and 14 are divisible by 2, while 21 is divisible by 3, and 21 and 14 are divisible by 7.
Hope this helps!

So, to begin, we can set the scenario into an equation to solve for the amount of magnets that Sarah had...

Joseph had 28 magnets, plus an unknown amount, x :

28 + x

Sarah had 157, plus the same unknown amount.

157 + x

Also, Sarah had four times the amount of Joseph at the end:

4(28 + x)

As a full equation:
