17.7m/s
Explanation:
Given parameters:
Height of branch = 16m
Unknown:
Velocity before falling = ?
Solution:
We are going to use the appropriate motion equation to solve this problem.
The bird is falling in line with the action of gravity.
Initial velocity is 0 for the bird.
Let the velocity during flight = V;
Then;
V² = U² + 2gH
since U = 0
V² = 2gH
V is the unknown velocity
H is the height of fall
g is the acceleration due to gravity
V = √2gH = √ 2x9.8 x 16 = 17.7m/s

Answer:
The time taken by the rock to reach the ground is 0.569 seconds.
Explanation:
Given that,
A student throws a rock horizontally off a 5.0 m tall building, s = 5 m
The initial speed of the rock, u = 6 m/s
We need to find the time taken by the rock to reach the ground. Using second equation of motion to find it. We get :
So, the time taken by the rock to reach the ground is 0.569 seconds. Hence, this is the required solution.
Answer:
True
Explanation:
Objects falling through the air experience a force of opposition called air resistance
Here Power = Voltage * Current
So, Voltage = Power/Current
Put the values,
V = 240/2
V = 120 V
In short, Your Final Answer would be: 120 Volts
Hope this helps!
