The three quantities are: acceleration, initial velocity and time
1. Acceleration
We can find the acceleration using Newton's Second Law of Acceleration:
F = ma
(8,000 N) = (70 kg)(a)
Solving for a,
<em>a = 114.286 m/s²</em>
2. Initial Velocity
For this quantity, we use the equation for rectilinear motion at constant acceleration.
2ax = |v² - v₀²|
where
x is the distance
v is the final velocity
v₀ is the initial velocity
2(114.286 m/s²)(0.60 m) = |0² - v₀²|
Solving for v₀,
<em>v₀ = 11.71 m/s</em>
3. Time
We can determine time fro the formula of acceleration:
a = |v - v₀|/t
114.286 m/s² = |0 - 11.71|/t
Solving for t,
<em>t = 0.102 seconds</em>

Answer:
Given:
Mass (m) = 75 kg
Height (h) = 10 m
Acceleration due to gravity (g) = 9.8 m/s²
To Find:
Potential Energy (PE)
Explanation:
The formula for potential energy due to gravity:
Substituting value of m, g & h in the formula:
This is a question volumetric flow rate.
In 1 second, water rises with 0.4 in.
Additionally,
Volume filled in 1 second = A*0.4, A = surface area of the circular cylinder.
Where,
A = πR^2 = π*3^2 = 9π in^2
Therefore,
Volumetric flow rate = 9π*0.4 = 11.31 in^3/s
In terms of liters/s,
1 in^3 = 0.0163871 litres
Then,
11.31 in^3/s = 11.31*0.0163871 ≈ 0.19 l/s
Answer:
Explanation:
<u>Mass and Weight</u>
The mass of an object is a measure of the object's amount of matter it contains. It's expressed in Kilograms or similar units.
The weight of an object is a measure of the force exerted on the object by gravity. It's often expressed in Newtons or similar units.
The formula to calculate the weight of an object with known mass m is:
W = m.g
Where g is the acceleration of gravity in the place it's located. We are given the mass of an electron:
On Earth, the acceleration of gravity is:
Thus, the weight is:
