In a lab investigation, one group of students (group a) measures the speed or a 0.1 kg toy cat w vc212
m/s at the bottom of a ramp. another group of students (group b) measures the speed of the car to be 3
m/s at the bottom of the ramp. the car's starting position at the top of the ramp is 1 m high.
a. what is the potential energy of the car at the beginning of the experiment before its speed is
measured?

if they have a finite resultant

wavelength divides in half and speed stays the same.

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.
