Explanation:
It is given that, a batter hits a pop-up to a fielder 93 m away, range of the projectile, R = 93 m
The ball remains in the air for 5.4 s, the time of flight is 5.4 s
Time of flight :
Maximum height of the projectile :
We need to find H.
So,
So, it will rise to a height of 35.72 m.
Answer:
69.28N
Explanation:
horizontal force
Cos 60°= F(horizontal)/80N
If we cross multiply, we have
F(horizontal)= 80 cos 60°
= 40N
vertical forces
Sin 60°= F(vertical)/80N
If we cross multiply we have
F( vertical) = 80 sin 60°
= 69.28N
Therefore, the vertical force is 69.28N
Answer:
Size is not considered a physical property because it is not measurable with concrete data, but a compound of height, weight and volume, which are physical properties by their own.
A physical property is, according to an initial understanding, an individual property, that is, which is linked in particular to any substance.
A physical property has the characteristic of being able to be measured or observed without affecting the composition or integrity of the respective substance. Some examples of physical properties are mass and volume.
Answer:
Efficiency of a machine is how well the machine works and what the machine is capable of doing.
Mechanical advantage=Load/Effort.
720/180=4
