A15.0 volt storage battery is connected to three resistors, 7.75? , 15.5? , and 21.7? , respectively. the resistors are joined in series. what is the current in the circuit?

3661.3 N/m

Explanation:

we can solve the problem by using the law of conservation of energy.

Initially, all the energy of the system is stored as elastic potential of the spring, which is given by

where k is the spring constant and x=1.69 cm=0.0169 m is the compression of the spring.

Later, when the spring is released, all the energy is converted into gravitational potential energy of the toy, which at its highest point is equal to

where m=104 g=0.104 kg is the mass of the toy, g=9.8 m/s^2 is the acceleration of gravity, and h=51.3 cm=0.513 m is the height reached by the toy.

Using the conservation of energy, we can write:
