Answer:
The duration, t = 3.53 seconds
Explanation:
The following information is provided:
The equation to calculate the time t is expressed as:
...... (1)
Where
s denotes the distance in feet
We are to determine the duration taken by the stone to fall a distance of 200 feet, where s = 200 feet
Substituting the value of s into equation (1) yields:

t = 3.53 seconds
Thus, the time taken by the object is 3.53 seconds, which provides the required answer.

Answer:
0.6
Explanation:
The formula for the volume of a sphere is 
Thus 
The radius of the disk is 
Applying angular momentum conservation;
The
of the sphere = 
of the disk = 

= 0.6
Response: 800N
Clarification:
Provided data:
Ball mass = 0.8kg
Contact duration = 0.05 seconds
Final and initial speed = 25m/s
The average force exerted by the ball on the wall can be calculated using the following relationship:
Force (F) = mass (m) * average acceleration (a)
a= (initial velocity (u) + final velocity (v))/t
m = 0.8kg
u = v = 25m/s
t = contact time of the ball = 0.05s
Thus,
a = (25 + 25) ÷ 0.05 = 1000m/s^2
Hence,
The average force magnitude (F)
F=ma
m = ball mass = 0.8
a = 1000m/s^2
F = 0.8 * 1000
F = 800N
