Answer:
66.6 kg
Explanation:
The weight of a person at Earth's surface is given by
where
m is the mass of the person
is the acceleration of gravity
The person in the problem has a weight of
W = 653 N
Therefore, we can rearrange the equation to find his mass:
Wrap around a metal with wire instead of using wire alone.
Answer:
The unrealistically large acceleration experienced by the space travelers during their launch is 2.7 x 10⁵ m/s².
How many times stronger than gravity is this force? 2.79 x 10⁴ g.
Explanation:
given information:
s = 220 m
final speed, vf = 10.97 km/s = 10970 m/s
g = 9.8 m/s²
he unrealistically large acceleration experienced by the space travelers during their launch
vf² = v₀²+2as, v₀ = 0
vf² = 2as
a =vf²/2s
= (10970)²/(2x220)
= 2.7 x 10⁵ m/s²
Compare your answer with the free-fall acceleration
a/g = 2.7 x 10⁵/9.8
a/g = 2.79 x 10⁴
a = 2.79 x 10⁴ g
<span> In 1 day there are 24 hours x 60 min/hour x 60 seconds/min = 86 400 seconds
So divide 9.39 x 10^9 by 86 400 to determine the # of days there are
= (9.39 x 10^9) ÷ (8.64 x 10^4)
= (9.39 ÷ 8.64) x (10^9 ÷ 10^4)
= 1.0868055556 x 10^5
= 108 681 (nearest whole day) </span>
