Answer:
a) 980 N
b) 100 kg
c) 163.33 N
Explanation:
a)
The weight of the object on Earth is the product of its mass times the acceleration due to gravity, that is:
b)
The mass of the object on the moon, is exactly the same (100 kg) since mass is an inherited value of the object.
c)
Considering that the acceleration of gravity on the Moon is about 1/6 that we have on earth (g), then the weight of the object on the Moon becomes:
Answer:
The velocity just before hitting the ground is
Explanation:
From the question we are told that
The initial speed is
The final speed is
From the equations of motion we have that
Where s is the distance travelled which is the height of the cliff
So making it the subject of the the formula we have that
Where a is the acceleration due to gravity with a value
So
Now we are told that was through horizontally with a speed of
Which implies that this would be its velocity horizontally through out the motion
Now it final velocity vertically can be mathematically evaluated as
Substituting values
The resultant final velocity is mathematically evaluated as
Substituting values
Hi there!
Assuming the track is frictionless:
Cancel out the masses and rearrange to solve for velocity:
Plug in the given height and let g = 9.8 m/s²:
