g The system is released from rest with no slack in the cable and with the spring unstretched. Determine the distanced s traveled by the 30-kg cart before it comes to rest (a) if m approaches zero and (b) if m

Solution :

It is given that a system is released from rest where no slack is attached to the cable and the spring is unstretched.

Mass of the cart = 30 kg

Applying the conservation of energy of the system,

Loss of the gravitational potential energy (PE) = the energy stored in the spring.

i.e.,

       x = 1.98

Therefore the distance travelled by the 30 kg cart is 1.98 m.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
