Answer:
its 1/2 the mass of the object times by its velocity ^ 2
Answer:
The impulse on the ball delivered by the floor is 2.52 kg-m/s.
Explanation:
Given that,
Mass of the ball, m = 0.22 kg
It is dropped from an initial height of 1.80 m. It rebounds back after colliding with the floor to a final height of 1.50 m. Initial velocity and final velocity can be calculated using conservation of energy as :

Final velocity,

As the ball rebounds, v = -5.47 m/s
We need to find the impulse on the ball delivered by the floor. We know that impulse is equal to the change in momentum as follows :

So, the impulse on the ball delivered by the floor is 2.52 kg-m/s.
Answer:
it could lead to riot
it could lead to uncertainty of life and property
Answer:
B
Explanation:
because. it reduces the distance between the earth
Answer:
1.10 m
Explanation:
First, find the time it takes to land.
Given, in the y direction:
Δy = 1.12 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(1.12 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.478 s
Next, find the distance traveled in that time.
Given, in the x direction:
v₀ = 2.30 m/s
a = 0 m/s²
t = 0.478 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.30 m/s) (0.478 s) + ½ (0 m/s²) (0.478 s)²
Δx = 1.10 m
