Answer:
below
Explanation:
Net accelerating force becomes 12-8 = 4 N
F = ma
4 = 2 * a
a = 2 m/s^2

Answer is D. both A and C.</span>
Answer:
8000J
Explanation:
The kinetic energy of the car lost during breaking are converted to thermal energy and are gained by the brakes.
Kinetic energy loss by car = thermal energy gained by brakes.
∆K.E = ∆T.E ....1
The Kinetic energy loss by car can be expressed as;
∆K.E = K.E1 - K.E2
Initial K.E = K.E1 = 10000J
Final K.E = K.E2 = 2000J
∆K.E= 10000J - 2000J = 8000J
From equation 1,
∆K.E = ∆T.E
∆T.E = 8,000J
thermal energy gain by brakes = 8,000J
The angular acceleration of the potter's wheel is 0.067 rad/s².
The given parameters:
- Final angular speed, ωf = 0.4 rev/s
- Time of motion, t = 37.5 s
<h3>What is angular acceleration?</h3>
- Angular acceleration of an object is the rate of change of angular speed of the object.
The angular acceleration of the potter's wheel is calculated as follows;
Thus, the angular acceleration of the potter's wheel is 0.067 rad/s².
