Answer:
the apparent weight of the astronaut in the rocket is 3723 N.
Given:
acceleration = 34 [tex]\frac{m}{s^{2} }[/tex]
mass of astronaut = 85 kg
To find:
Apparent weight of the astronaut = ?
Solution:
Total weight of the astronaut in a rocket is given by,
W = w + F
W = apparent weight of the astronaut
w = weight of astronaut on earth surface = mg
F = force acting on the astronaut = ma
W = mg+ma
W = m (g+a)
W = 85 (9.8 + 34)
W = 3723 N
Thus, the apparent weight of the astronaut in the rocket is 3723 N.
Answer:
2057N
Explanation:
Mass (M) = 85kg
Acceleration (a) = 34.0m/s²
g = 9.8m/s²
Weight = mass * acceleration
Weight = 85 * 34 = 2890N
Force acting against the astronaut = M*g
F = 833N
Weight of the astronaut = weight of the astronaut inside the rocket (thrust) - force of gravity acting on him
Weight = Ma - Mg = M(a-g)
Weight = 2890 - 833 = 2057N
