Object 1 starts at 25 m and moves with a velocity of - 5.1 m/s. Object 2 starts at 13 m and moves directly toward object 1. The two objects collide 0.62 s after starting. What is the velocity of object 2?
What is the position of the objects when they collide?

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.

3. dark matter

empty space could also be a simple vacuum
