Si units or Systeme' de Internationale' is a widely adopted unit system in measuring basic and derived dimensions In this case, the SI units here are kilograms, meter and seconds. Pounds is an English unit. mass is the measure of <span>how much matter an object contains, hence the answer is A. 43 kg.</span>
Answer:
Explanation:
The Work-Kinetic Energy Theorem states that the work done on a particle of mass "m", equals the particle's change in Kinetic Energy (final Kinetic Energy of the particle "" minus the initial Kinetic energy of the particle ""), and it is expressed as:
where we have used the explicit form of the KE of a particle of mass m and velocity . Of course, stands for the final velocity of the particle, and for the particle's initial velocity.
Answer:
G is a universal constant of gravitation whose unit is Newton per meter square per kilogram square (Nm^2kg^-2)
Answer:
v = √(2gh)
Explanation:
Given:
Δy = h
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2gh
v = √(2gh)
You can also prove this with conservation of energy.
PE = KE
mgh = ½mv²
v = √(2gh)
Answer: the <em><u>distance</u></em> of our walk home.
Explanation:
In Physics when we speak of distance we refer to the space traveled that is always measured on the trajectory, while displacement refers to the space from an initial position to a final position regardless of the path. When the path is a straight line, the space traveled is equal to the module of the displacement.
