Answer:
The car is decelerating and its acceleration is negative.
Explanation:
First thing to consider. The car traveling direction is not important to answer the question.
Second, there are two affirmations on each sentence. So, lets take definitions:
Deceleration: Reducing the acceleration, from one value to another. No matter if the acceleration for the moment is positive or negative.
Acceleration negative: the driver is applying a force to make speed=0, the sign of this force must negative in order for the car to stop, other way it will go faster. Acceleration is the change rate of speed, if the speed is going down, the total acceleration until cars stops must be negative.
Answer:
A. 1.125×10^-7 kgm^2
B. 6.64875 rad/s
Explanation:
The moment of inertia is defined as a quantity expressing a body's tendency to resist angular acceleration, which is the sum of the products of the mass of each particle in the body with the square of its distance from the axis of rotation.
A. Moment of inertia = m1✖r1^2
=1.80 x (2.5x10^-4)^2
= 6.25x10^8 x 1.80
= 1.125 x 10^-7 kgm^2.
B. w is represented as Angular speed.
V is velocity, T is time in period.
Velocity= distance / time.
V= 2.5x10^-4 / 0.940
V= 2.6595 metre per seconds
w= v/r
w= 2.6595 / 0.400
w= 6.64875 rad/s.
<span>When there is a fire, you need to be able to get at the extinguisher easily and quickly.
</span>The best place to store a fire extinguisher on a boat is in a readily accessible location. The extinguisher should <span>not be covered up or closed in a storage unit, but in an open area. </span><span>Monthly inspections are necessary to keep your fire extinguisher working properly.</span>
If you give it unbalanced force it would go up and if you can't give it enough it will stay a balanced force
