Answer:
Ft = 0[N]
Explanation:
To understand this problem we must perform an analysis of forces on the X axis, which coincides with the axis of forces of dogs.
In this way performing a sum of forces on the X-axis we will have (newton's third law):
From this analysis we can see that the resulting or total force is equal to zero, since there is no movement.
m = mass of the ball being raised
h = height to which the ball is raised = 0.5 m
v₀ = initial speed given to the ball = 3
v = final speed of the ball at its lowest position = ?
using conservation of energy
final kinetic energy at the lowest point = initial kinetic energy + initial potential energy
(0.5) m v² = (0.5) m v₀² + mgh
dividing each term by "m"
(0.5) v² = (0.5) v₀² + gh
inserting the values
(0.5) v² = (0.5) (3)² + (9.8) (0.5)
v = 4.34 m/s
The answer is cesium oxide
