A tow truck drags a stalled car along a road. The chain makes an angle of 30° with the road and the tension in the chain is 1000
1 answer:
To develop this problem it is necessary to apply the work theorem. This tells us that the energy on a body is equivalent to the product between the Force applied on it and the distance traveled. The vector product of these measures can be expressed as
And its magnitude is equivalent to
Where is the angle formed between the applied force and the line of displacement of the body.
Our values are given as,
Applying this value and replacing we have,
Therefore the work done by the truck is 1.299 Mega Jules

Explanation:
Given
Wheels are rotating with constant angular velocity let say
Presence of constant angular velocity show that there is no angular acceleration thus there is no tangential acceleration.
But any particle on the rim will experience a constant acceleration towards center called centripetal acceleration.
(a) yes, there will be tangential velocity which is given by
where r=radial distance from center
(b)tangential acceleration
there would be no tangential acceleration as velocity is constant
(c)centripetal acceleration
Yes, there will be centripetal acceleration given by
