2) A golf club is swung at a ball and hits the ball with a force of F newtons. Which statement below is correct. AThe ball will apply a force back on the club of F newtons
BThe ball will apply a larger force on the club due to the conservation of momentum laws
CWithout knowing the exact force it cannot be determined
DThe ball will apply less force on the club because it is much small in size and mass compared to the club

B (I did this last year!:')

Explanation:

In physics, the term conservation refers to something which doesn't change. This means that the variable in an equation that represents a conserved quantity is constant over time. It has the same value both before and after an event.

There are many conserved quantities in physics. They are often remarkably useful for making predictions in what would otherwise be very complicated situations. In mechanics, there are three fundamental quantities that are conserved. These are momentum, energy, and angular momentum. Conservation of momentum is mostly used for describing collisions between objects.

nah.   i'm just sleepy.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
