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.

Electrical current is defined as the flow of electric charge per unit time.
Answer: stop the experinment and begin again sometimes the result of the experiment may give you unexpected results due to the fact that you may have missed a certain step or you didn't follow the procedure accurately to the dot, hence it's important to redo the experiment and see if every step was followed accurately before you can discard the results or change the procedure.
Explanation:
Answer:
Moment of inertia of the system is 289.088 kg.m^2
Explanation:
Given:
Mass of the platform which is a uniform disk = 129 kg
Radius of the disk rotating about vertical axis = 1.61 m
Mass of the person standing on platform = 65.7 kg
Distance from the center of platform = 1.07 m
Mass of the dog on the platform = 27.3 kg
Distance from center of platform = 1.31 m
We have to calculate the moment of inertia.
Formula:
MOI of disk = 
Moment of inertia of the person and the dog will be mr^2.
Where m and r are different for both the bodies.
So,
Moment of inertia 
of the system with respect to the axis yy.
⇒ 
⇒ 
⇒ 
⇒ 
The moment of inertia of the system is 289.088 kg.m^2
Answer:
Average speed, v = 25 m/s
Explanation:
It is given that,
Distance travelled by the object, d = 50 meters
Time taken, t = 2 seconds
Average speed is defined as the total distance divided by total time taken i.e.
v = 25 m/s
So, the sped of the object is 25 m/s. Hence, this is the required solution.
