time to reach an angular velocity of 36.8 is 24.370 s.
<h3>
</h3><h3>What is angular acceleration?</h3>
The temporal rate at which angular velocity changes is referred to as angular acceleration. Naturally, there are two forms of angular acceleration, referred to as spin angular acceleration and orbital angular acceleration, just as there are two types of angular velocity, namely spin angular velocity and orbital angular velocity. As opposed to orbital angular acceleration, which is the angular acceleration of a point particle around a fixed origin, spin angular acceleration describes the angular acceleration of a rigid body about its centre of rotation.
w(t) = w(0) + α*t
also w(0) =0
=> time = 36.8/1.51= 24.370 s

Answer:
The speed of the animals is 1.64m/s.
Explanation:
Let us work with variables and call the mass of the two rats
and
, and the length of the rod
.
Using the law of conservation of energy, which says the potential energies of the rats must equal their kinetic energies, we know that when the rod swings to the vertical position,

,
solving for
, we get:

Putting in the values for
,
,
, and
we get:


Therefore, as the rod swings through the vertical position , the speed of the rats is 1.64 m/s.
Kinetic Energy
How to calculate
Kinetic energy is given by K.E.

Where
- m is denoted to mass
- v is denoted to velocity
If the absolute pressure of a gas is 550.280 kPa, its gage pressure is
<span>
a. 101.325 kPa.
b. 448.955 kPa.
c. 651.605 kPa.
d. 277.280 kPa.</span>
The answer is B.
Answer:
B Negative
Explanation:
Its negative because when your going 25 mph your moving faster and when your coming up to the stop sign you will start to slow down going 10 mph then 0 mph when you reach the stop sign so it will be negative.
