What two quantities are crucial to quantifying the translational kinetic energy of an object?

Physics
1 answer:
Ostrovityanka [42]3 years ago
3 0

Answer:

Moment of inertia and angular velocity.

Explanation:

The translational kinetic energy of an object is possessed when the object is showing rotational motion. It can be given by the formula as :

KE=\dfrac{1}{2}I\omega^2

Here,

I is the moment of inertia of the object

\omega is the angular velocity of the object

So, the translational kinetic energy of an object is given by moment of inertia and angular velocity of the object. Hence, this is the required solution.

The blades of a fan running at low speed turn at 250 rpm. When the fan is switched to high speed, the rotation rate increases un
fgiga [73]

Answer:

1.82 rad/s².

Explanation:

Applying,

α = (ω₂-ω₁)/t..................... Equation 1

Where α = angular acceleration of the fan blades, ω₂ = final angular velocity of the fan blades, ω₁ = initial angular velocity of the fan blades, t =  time.

Given: ω₂ = 350 rpm = (350×0.1047) rad/s = 36.645 rad/s. ω₁ = 250 rpm = (250×0.1047) rad/s = 26.175 rad/s, t = 5.75 s.

Substitute into equation 1

α = (36.645-26.175)/5.75

α = 10.47/5.75

α = 1.82 rad/s².

Hence the magnitude of the angular acceleration of the fan blades = 1.82 rad/s²

A race car has a centriple acceleration of 15.625 m/s as it goes around a curve if the curve is a circle with radius 40 m what’s
Elanso [62]

Answer:

25 m/s

Explanation:

Centripetal acceleration is the square of the tangential velocity divided by the radius.

a = v² / r

15.625 m/s² = v² / (40 m)

v² = 625 m²/s²

v = 25 m/s

The speed of the car is 25 m/s.

3. Calculate the speed for a car that went a distance of 155 kilometers in 3 hours
Sladkaya [172]

Answer:This is an explanation

for 150 km its all ik i tried hard ty

Explanation:The car covers 150 km in 3 hours or 3*60 = 180 minutes.

So in 12 min the car will cover (12/180)*150 = 10 km.

Please answer<br>my quastions​
Neko [114]

Answer:

a) 120 N

b) 5 N

c) 0.2 N

d) Mass remains the same, and weight decreases.

Explanation:

<em>Use the formula W = mg, where mass is in kg, and gravitational field strength in N/kg.</em>

a)

W = mg

= 12 × 10

= <u>120 N</u>

b)

500 g = 0.5 kg

W = mg

= 0.5 × 10

= <u>5 N</u>

c)

20 g = 0.02 kg

W = mg

= 0.02 × 10

= <u>0.2 N</u>

d)

<u>Mass remains the same, and weight decreases.</u>
