Answer:
All the objects experience the same acceleration
Explanation:
According to Newton's law of universal gravitation, we have the gravitational force F given by the relation;
Where;
G = The universal gravitational constant
M₁ = The mass of the Earth
m₂ = The mass of the object in the Earths gravitational field
R = The radius of the Earth
Therefore, we have;
Which gives;
Therefore, based on the above calculation, all three object will have the same acceleration due to gravity, g, when air resistance is ignored.
Answer:
Explanation:
25 cycles/s (5 s) = 125 dots
Tape does Repetitious motion.
It might possibly be harmonic motion, but we do not have enough information to say for certain.
Impulse=force x time
force=mass x acceleration due to gravity
force=
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Hope this helps you.
Answer:
0.0083km or 8.3m
Explanation:
Given parameters:
Distance = 5km
Time = 10min
Unknown:
Distance moved in 1sec = ?
Solution:
To solve this problem, let us first find the speed of the motorbike.
Speed =
Speed = = 0.5km/min
So;
In 1sec:
60 sec = 1 min
1 sec = min
Distance moved in 1sec = speed x time
Distance moved = 0.5km/min x min = 0.0083km or 8.3m
