Answer:
Jupiter
Explanation:
Since the mass of Jupiter is the greatest from the given choices, it will exert the most force on any object orbiting 100km above its surface.
This is compliance with the Newton's law of universal gravitation which states that "the force of attraction between two bodies is directly proportional to the magnitude of their masses and inversely proportional to the distances between them".
- Therefore, the more the masses of two bodies, the higher the gravitational attraction
- Since the distance is the same, the planet with the greater mass will exert the most force on the satellite.
Answer:
50kg
Explanation:
F=ma
95N (kg/(m/s^2)) = m * 1.9 m/s^2
95/1.9 = 50kg
Answer:
<h2>For 24 seconds
force exerted is 5092 N towards opposite direction of motion of bus.</h2><h2>For 3.90 seconds
force exerted is 31333 N towards opposite direction of motion of bus.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 20 m/s
Final velocity, v = 0 m/s
Case 1:-
Time, t = 24 s
Substituting
v = u + at
0 = 20 + a x 24
a = -0.8333 m/s²
Force = Mass x Acceleration = 6110 x -0.8333 = -5092 N
Force exerted is 5092 N towards opposite direction of motion of bus.
Case 2:-
Time, t = 3.90 s
Substituting
v = u + at
0 = 20 + a x 3.90
a = -5.13 m/s²
Force = Mass x Acceleration = 6110 x -5.13 = -31333 N
Force exerted is 31333 N towards opposite direction of motion of bus.
