The height of the rail on top of the press box where the ball was dropped from is 11.025 m.
The given parameters:
- Time of motion of the ball, t = 1.5 s
- Let the height of the rail = h
<h3>Maximum height of fall;</h3>
- The maximum height through which the ball was dropped from is calculated by applying second equation of motion;
Thus, the height of the rail on top of the press box where the ball was dropped from is 11.025 m.

Answer:
B. The larger force causes more acceleration than the smaller.
Explanation:
For example, let me use a child and a grown up. The child represents the smaller force while the grown up represents the larger force. If they are pushing the same object of different sides, obviously the side with the grown up will push and move to the side of the child because it is stronger.
Answer:
Explanation:
The solution of the question has been put in attachment.
Answer:
t / τ₀ = 2.9
the time constant has to be multiplied by approximately three
Explanation:
The expression for long of a capacitor is
q = q₀ (1- e (-t/τ₀)
Where q is the charge and τ₀ is the time constant. What is found for when the initial capacitor charge at 63.5% (e⁻¹) of the maximum charge
In our case we are asked that the load be 94.5%, this means that
q/q₀ = 94.5%
q/q₀ = 0.945
Let's replace and calculate
q/q₀ = 1 - e (-t/τ₀)
0.945 = 1 - e (-t/τ₀)
(-t /τ₀) = ln (1 -0.945) = ln (0.055)
t / τ₀ = 2.9
the time constant has to be multiplied by approximately three for this charge
I = V / R = 9v / 36ohms = 1/4 Ampere
