Answer:
72.22 N
Explanation:
F = weight
m = mass of body
M = mass of earth
R = radius of earth
G = universal constant of gravitation
F_1= 650 N
F_1 = GMm/R^2
two earth radius above the surface of the earth:
F_2= GMm/(3R)^2= GMm/9R^2= F_1/9= 650/9
=72.22 N

Answer:
36,000j
Explanation:
W= P•t
120•300= 36000
I checked my answer with P= W/t and got the right answer
hope this helps
41.2 = h-1/2g(t-1)^2
<span> {-h = -1/2gt^2-1/2g+g*t-41.2
</span><span> {h = 1/2gt^2
</span><span> summing them up
</span><span> 0 = -1/2g+g*t-41.2
</span><span> 41.2 +4.9 = g*t
</span><span> t = 46.1/9.8 = 4.70 sec
