Answer:

(a) 0.40 rad/s

(b) 0 m/s

Explanation:

Since the car is moving at a constant speed, the tangential acceleration of the car is 0 m/s.

To find its angular velocity, we use the equation ω = v/r.

Therefore, the angular velocity ω = 80/200 = 0.40 rad/s.

Which three factors are used to calculate gravitational potential energy?
Elis [28]

Explanation:

PEgrav = m *• g • h

In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
