Answer: False
Explanation: They can see it by karst topography!
100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s
Answer:
vertical force cannot change the velocity on the x-axis. t =x/v₀ₓ
Explanation:
The force is a vector magnitude, so the forces on the x-axis affect the acceleration on this axis. Consequently a vertical force cannot change the velocity on the x-axis.
= m g
Fₓ = 0
The horizontal velocity in projectile motion is constant, if we neglect the air resistance, so it can be used to find the time of a horizontal displacement
x = v₀ₓ t
t =x/v₀ₓ
The only magnitude that is the same for both movements is the time that is a scalar
Because it has a small hole and air is like water, an area of higher pressure wants to move to a lower pressure area.
Then the magnitude of the net force is the difference between the two forces,
and its direction is the same as the direction of the greater one.
