Answer:
4058.48594 m/s
Explanation:
M = Mass of Mars =
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Initial velocity = 2910 m/s
= Final velocity
m = Mass of satellite
= Initial distance of satellite =
= Final distance of satellite =
The kinetic and potential energy of the system is conserved
Final velocity is 4058.48594 m/s
1) 20 min = 1/3 h
2) distance = speed * time = 12 * 1/3 = 4 km
Answer:
Convex and Virtual
Explanation:
A concave lens makes things appear smaller while a convex can make it magnified while being virtual. It appears right side up which makes it virtual.
Hope you do a good job!! :)
Answer: -2.9 m/s
Explanation:
If we assume that no external forces act during the collision, total momentum must be conserved.
If the collision is completely inelastic, so both masses continue stuck together after it, we can consider that the system behaves like it were a single mass, with a single speed.
So, we can write the following:
p₁ = p₂ ⇒ m₁.v₁ + m₂.v₂ = (m₁ + m₂) vf
Replacing by the values, and solving for vf, we get:
vf = (19 kg. 1.5 m/s + (8 Kg. (-13.5 m/s)) / 19 kg + 8 Kg = -2.9 m/s.
