Two carts collide elastically. The second cart is pushed horizontally in the positive direction on a frictionless surface with a force of F2. The carts have masses m1 and m2, respectively. What acceleration does the first cart feel during the collision? Remember it's a vector.

Explanation:

First of all, we notice that the collision is elastic: this means that there are no external forces acting on the system, as the total momentum and the total kinetic energy of the system are conserved.

The force acting on the cart 2 is

According to Newton's third law of motion:

"When an object 1 exerts a force on another object 2, then object 2 exerts an equal and opposite force on object 1"

Therefore, if we call the force exerted on cart 1 during the collision, we can write

According to Newton's second law of motion, the net force acting on an object is equal to the product between its mass (m) and its acceleration (a):

So for cart 1 we have:

And som the acceleration of cart 1 is

Where the negative sign means that the direction of the acceleration of cart 1 is opposite to the direction of the force F2.

hypothesising or postulating

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
