Answer:
1] 8500000 = <u>8.5 × 10⁶</u>
2] .000072 = <u>7.2 × 10⁻⁵</u>
3] 5.3 × 10⁴ = <u>53000</u>
4] 2.8 × 10⁻³ = <u>0.0028</u>
5] Velocity = 
V = 
<u>V = 5 m/s</u>
6] Acceleration = 
A = 
A = 
<u>A = 3 m/s²</u>
Answer:
Explanation:
The weaker force is pulling to direction East(450 newton)
the net force is (500-450=50 newton) and will move toward west ( in 500 newton direction)
They both have kinetic energy because they are both moving and have force.
Hope this helped! :)
The moment of inertia is 
Explanation:
The total moment of inertia of the system is the sum of the moment of inertia of the rod + the moment of inertia of the two balls.
The moment of inertia of the rod about its centre is given by

where
M = 24 kg is the mass of the rod
L = 0.96 m is the length of the rod
Substituting,

The moment of inertia of one ball is given by

where
m = 50 kg is the mass of the ball
is the distance of each ball from the axis of rotation
So we have

Therefore, the total moment of inertia of the system is
