Answer:that your subconscious is trying to tell you something
Explanation:
The ball that is thrown into the air with a velocity of 44 ft/s, its height in feet t seconds later is given by the following equation:
y=46 ft/s * t - (32.17 ft/s² * t²/2)
The height in (ft) at a time (t) of a body that has been thrown with a certain velocity and is in vertical motion is given by the following equation:
y = vi * t - (g* t²/2)
Where:
- y = height
- vi = initial velocity
- g = gravity
- t = time
Information about the problem:
- vi = 46 ft/s
- g = 32.17 ft/s²
- y =?
- t = t
Applying the height formula we get:
y = vi * t - (g* t²/2)
y = 46 ft/s * t - (32.17 ft/s² * t²/2)
<h3>What is the vertical upward launch?</h3>
It is the movement described by an object that has been thrown vertically upwards in which the height and the effect of the force of the earth's gravity on the thrown object are considered.

Answer:
T = 2490 newton
Explanation:
Given that,
Mass of a person, m = 50 Kg
Speed of the swing at the lowest point, v = 10 m/s
Length of the rope, r = 2.5 m
Tension formula is given by
T = mg + ma N
where, T - Tension in the string
m - mass of the body
g - acceleration due to gravity
a - acceleration of the body
Since the person is swinging, the acceleration of the body is given by
a = v²/r m/s²
= 10/2.5 m/s²
a = 40 m/s²
Substituting in T
T = 50 Kg x 9.8 m/s² + 50 Kg X 40 m/s²
= 490 + 2000 Kg m/s²
T = 2490 newton
Therefore the tension in the rope is 2490 newton
Answer: A is the correct option.
