Answer:
25.51 m
Explanation:
Notably, gravitational potential energy is measured in the same units as kinetic energy, namely kg m2/s2.
What kinetic energy in maximum height?Because of some horizontal velocity, kinetic energy is least but not zero at maximum height. In light of the fact that the amplitude of the y-component of velocity rises when falling, KE then again increases with distance.
At the highest height, there is only potential energy because there is no vertical velocity and therefore no vertical kinetic energy.When an item reaches its maximum height, its velocity decreases to zero, and it begins to fall in the direction of the gravitational acceleration.
Therefore, P.E. = mgh is the formula for gravitational force, where m is mass in kilograms, g is acceleration due to gravity (9.8 m/s2 at the earth's surface), and h is height in meters.

Is it true that acceleration occurs when there is a change in speed
Answer:
Acceleration is the rate of change of velocity.
Explanation: For example, acceleration is measured in m/2^2 or meters per second squared. That can also be split up into 2 components. M/s is how speed is measured, and since acceleration is the rate of change of velocity, m/(s*s). You could say that since acceleration is m/s^2, it can also be represented as how much the speed increases over 1 second. if there was an acceleration of 3 m/s^2, the rate of change of speed would be 3m/s every second, meaning that the object would speed up 3m/s every second that passes by.
Hope this helps!
In the acceleration versus time graph above, what is the change in
velocity from 0 to 2s?
Hello!
[tex]\large\boxed{4 m/s}[/tex]
Find the change in velocity by finding the area under the line in an acceleration v. time graph:
We can divide the area underneath the interval 1 - 2 seconds into a rectangle and a triangle. Use the formulas:
A = l × w
A = 1/2(b · h)
We can solve for the rectangle first:
A = 2 × 1 = 2
Do the remaining area using the formula for a triangle:
A = 1/2 (2 · 2) = 2
Add the areas together:
2 + 2 = 4 m/s.
The Δv (change in velocity) is 4 m/s.

A weightlifter completes a series of lifts with a 700 N weight. In one lift, he raises the weight to a height of 2.5 m off the ground. The lift takes 0.60 s to complete. What power does the weightlifter have been performing this lift
Answer:
The output power the weightlifter is 2916.67 W.
Explanation:
Given;
weight lifted, W = 700 N
height the weight is lifted, h = 2.5 m
time taken to lift the weight, t = 0.60 s
The output power the weightlifter is calculated as;
Power = Energy applied / time taken
Energy applied = weight lifted x height the weight is lifted
Energy applied = 700 x 2.5
Energy applied = 1750 J
Power = 1750 / 0.6
Power = 2916.67 J/s = 2916.67 W.
Therefore, the output power the weightlifter is 2916.67 W.

Answer:
Acceleration & 9.8 M/S/S
Explanation:
Pretty self explanatory for question 2, speeding up can easily be related to acceleration, and for question 3
"Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth's surface."

A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.
The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.
