Horizontal and Vertical are the two motions that combine to produce projectile motion.
A barometer is used to measure air pressure!
Answer:
- Because the mass is also 6 times greater, so the acceleration is the same.
Explanation:
Force is mass multiplied by acceleration. This is (in one dimension):
Now, we can see what acceleration will every rock feel:
Lets call the force over the first rock, that has a mass , and lets call the force over the second rock, that has a mass . We can write the following equations:
and
.
We also know that:
, so:
.
But the mass is also six times greater.
so...
.
Now, lets obtain the acceleration. For the first rock we got:
and for the second rock
But this is the same acceleration that the first rock has! So, the kinematics will be the same.
Answer:
364.56 N
Explanation:
W = mg
The gravitational force on Earth is about 9.8 N.
W = (37.2 kg)(9.8 N)
W = 364.56 N
