NEC Projectile Motion Activity
You will be given a dart gun and up to three meter sticks Devise a step by step method for
finding the initial velocity of the art using only this equipment List the measurements you will
need to take, any assumptions you make and any formulas or calculations you will use to find
Vi then i need measurements needed

assumptions made

formulas or calculations used

step by step procedure

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.
