Answer:
<em>The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile</em>
Explanation:
<u>Kinetic Energy
</u>
Is the capacity of a body to do work due to its speed and is computed by
We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:
So its kinetic energy is
The mass of the fly is
To have the same kinetic as the automobile:
Solving for 
The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile
Answer:
The initial vertical velocity is zero, u = 0 m/s
Explanation:
Given;
height of the table, h = 0.55 m
horizontal distance traveled by the tennis, x = 0.12 m
Apply the following kinematic equation;
h = ut + ¹/₂gt²
where;
u is the initial vertical velocity = 0, since the tennis ball rolled off the edge of a table.
h = ¹/₂gt²
The time to fall from the vertical height is given by;
The initial horizontal velocity of the tennis is given by;
x = vₓt
vₓ = x / t
vₓ = (0.12) / (0.335)
vₓ = 0.358 m/s
Therefore, the initial vertical velocity is zero, u = 0 m/s and initial horizontal velocity, vₓ is 0.358 m/s
Answer:
t = 10.1 s
d = 2020 m
Explanation:
Time to drop from vertical rest
h = ½gt²
t = √(2h/g) = √(2(500)/9.8) = 10.1 s
d = vt = 200(10.1) = 2020 m
