Answer:
The normal force the ground exerts on the block, F = -300 N
Explanation:
Given data,
The block pulled up with a tension force, T = 100 N
The weight of the block, W = 300 N
The weight of the block is due to the force of attraction of gravitation.
The surface exerts a force that is equal and opposite to the force acting on the block due to gravitation.
The weight of the block,
W = mg
300 N
The normal force the ground exerts on the block,
F = - mg
= - 300 N
Hence, the normal force the ground exerts on the block, F = -300 N
Compared to terrestrial planets, jovian planets are more massive and lower in average density.
Answer:
The answer to your question is vf = 23.47 m/s
Explanation:
Data
a = 2.9 m/s²
vo = 0 m/s
d = 95 m
vf = ?
Formula
vf² = vo² + 2ad
Substitution
vf² = (0)² + 2(2.9)(95)
Simplification
vf² = 2(275.5)
vf² = 551
vf =
vf = 23.47 m/s
The mushroom will have a velocity of 23.47 m/s after it has been displaced 95 m.
The energy of its motion is its kinetic energy.
The energy of its position is its potential energy.
Together, I think they're the object's mechanical energy.
Answer:
7661.06 m/s
Explanation:
R = Radius of Earth =
h = Distance from the Earth = 420000 m
G = Gravitational constant =
M = Mass of Earth =
The orbital speed of the satellite is 7661.06 m/s
