In Grams it would be 509.85 (1 N=101.97g)
40 m/s ---Apex <span>is the magnitude of its velocity.</span>
Basic basic basic, fundamental, elementary, and basic.
Please memorize this <em>definition</em> of acceleration:
<em>Acceleration</em> = <em>(change in speed) </em><em>divided by</em><em> (time for the change)</em> .
For example: Goes from 0 m/s to 10 m/s in 5.0 sec.
Change in speed = (10 - 0) = +10 m/s
Time for the change = 5.0 sec.
Acceleration = (+10 m/s) / (5.0sec) = +2 m/s² .
Answer:
M = 3.485 kg
m = 1.605 kg
Explanation:
F = 0.98 x 10^-8 N
r = 19.5 cm = 0.195 m
M + m = 5.09 kg ...... (1)
By use of Newton's gravitational law
F = G m1 m2 / r^2
0.98 x 10^-8 = 6.67 x 10^-11 x M x m / (0.195)^2
M x m = 5.59
M - m = 1.88 .........(2)
By solving the equation (1) and equation (20, we get
M = 3.485 kg
m = 1.605 kg
