Answer:
Explanation:
F=ma
F in this case is the gravity acting on the 2kg object. Acceleration of gravity is 9.8 m/s^2. SF=ma, so
F = 2kg*(9.8 m/s^2) = 19.6 N
Now use this force to determine the mass of the object on the table:
F=ma
19.6 N (1N=kg*m/s^2) = m*(1.8 m/s^2)
m = 10.89 kg
If the object's velocity and acceleration have <em>opposite signs</em>, then the object is slowing down.
Well, when you want to accomplish a goal, you can't take forever to do it now can you? No. The purpose of setting a deadline for your goal is for motivation. You become motivated to do it, instead of putting it off for later. You want to get it done in a reasonable amount of time.
Answer:
v₂ = 5131.42 m/s
Explanation:
given,
radius of the planet = r₁ = 9.00×10⁶ m
mass of the satellite = m₁ = 68 Kg
orbital radius = r₁ = 8 x 10⁷ m
orbital speed = v₁ = 4800 m/s
mass of second satellite = m₂ = 84.0 kg
orbital radius = r₂ = 7.00×10⁷ m
orbital speed of second satellite = v₂ = ?
using orbital speed of satellite

so,

now,


v₂ = 5131.42 m/s
The orbital speed of second satellite is equal to v₂ = 5131.42 m/s
