11. You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s2 for acceleration due to gravity, wh
Natalka [10]

Displacement is d  



Vf² = Vi² + 2 g d  



(-20²) = (+10²) + 2 (-9.8) d  



-19.6 d = 300  



d = -15.3 m  



negative means lower



time is t  



d = Vi t + 1/2 g t²




-15.3 = 10 t + (-4.9) t²




4.9 t² - 10 t -15.3 = 0  



t = 3.06 s

The figure above shows a rod that is fixed to a horizontal surface at pivot P The rod is initially rotating
Lisa [10]

The angular speed is decreasing and direction of rotation clockwise of the rod immediately after time t.

<h3></h3><h3>What is angular speed ?</h3>

The rate of change of angular displacement is defined as angular speed.  It is stated as follows:

ω = θ t

Where,

θ is the angle of rotation,

t is the time

ω is the angular velocity

The torque is found as;l

\rm  T = F \times r

If the force is acting on the rod  from the three point is the same, the value of the torque is depends upon the radius or the perpendicular distance.

The perpendicular distance of the right force is grater. Hence, the force acting on the right side is more, and the rod will rotate clockwise.

Both the forces are acting downwards. Thus, the resultant force is the less due to which the speed is increasing.

Hence, the angular speed is decreasing and direction of rotation clockwise of the rod immediately after time t.

To learn more about the angular speed, refer to the link;

How does a decrease in thermal energy affect the particle motion in each state of matter
Valentin [98]
The thermal energy is proportional to the movement of the particles in every state.

Decreasing the thermal energy will decrease the movement.
