Answer:
ω = ω₀ + α t
ω² = ω₀² + 2 α θ
θ = θ₀ + ω₀ t + ½ α t²
Explanation:
Rotational kinematics can be treated as equivalent to linear kinematics, for this change the displacement will change to the angular displacement, the velocity to the angular velocity and the acceleration to the angular relation, that is
x → θ
v → ω
a → α
with these changes the three linear kinematics relations change to
ω = ω₀ + α t
ω² = ω₀² + 2 α θ
θ = θ₀ + ω₀ t + ½ α t²
where it should be clarified that to use these equations the angles must be measured in radians
Answer:
36 m³
Explanation:
From gas laws, at a constant temperature, the product of volume and pressure are directly proportional hence expressed as p1v1=p2v2 where p is pressure while v represent volume. Subscripts 1 and 2 represent the initial and respectively. Making v2 the subject then

Substituting 120 kpa for P1, 12m³ for V1 and 40 kpa for p2 then

Therefore, the volume will be 36 m³
The final velocity will be 19 m/sec.Option C is correct.
<h3>What is velocity?</h3>
The change of displacement with respect to time is defined as the velocity.
Velocity is a vector quantity. it is a time-based component. Velocity at any angle is resolved to get its component of x and y-direction.
From Newton's first equation of motion;

The final velocity will be 19 m/sec
Hence, option C is correct.
