Explanation:
The acceleration of an object (or a person, as in this case) is given by

where
v is the final velocity
u is the initial velocity
t is the time interval
In this problem,
u = 20 m/s
v = 40 m/s
t = 10 s
Therefore Jill's acceleration is

Answer:
I = 2.667 kg m²
Explanation:
The moment of inertia of a body can be calculated by the expression
I = ∫ L² dm
For high symmetry bodies the expressions of the moment of inertia are tabulated, for a rod with its axis of rotation at its midpoint it is
I =
m L²
let's calculate
I =
2 4²
I = 2.667 kg m²
Answer:
For example, a solid may become a liquid. This phase change is called melting. When a solid changes into a gas, it is called sublimation. When a gas changes into a liquid, it is called condensation. ... That allows the solid substance to have a definite volume and shape.
