Amy's weight = 55 kg also Amy's velocity = 3 m/sec. And Jenny's weight = 40 kg Jenny's velocity = -5 m/sec. their final mass = 55+40 = 95 kg is their final velocity that we want to find out.
Ect. but in conclusion the answer is 7/19 m/sec.
I hope this is correct >w< if it's not I am really sorry I mist up.
-0.9 -0.4. Make sense at all???
Answer:
The coefficient is same and constant is different
Answer:
The circumference of a circle with radius 3 is 3 times as big as the circumference of a circle with radius 1
Explanation:
Assume that the radius of the small circle is r
Increasing the radius by a factor of 3 means that the new radius of the large circle would be 3r
Circumference of circle can be calculated as follows:
circumference = 2*π*radius
For the small circle:
circumference = 2πr
For the large circle:
circumference = 2π(3r)
circumference = 6πr
Comparing the circumference of the two circles, we can deduce the increasing the radius by a factor of 3 will lead to the increase in the circumference of the circle by factor of 3 as well
Hope this helps :)
