Object 1 starts at 5.4 m and moves with a velocity of 1.5 m/s. Object 2 starts at 8.1 m and moves with a velocity of -2.2 m/s. The two objects are moving directly toward one another. The object with the greater

speed is Object

(ONLY WRITE THE NUMBER 1 OR 2 IN

THE RESPONSE BLANK). The two objects will collide at

of

GIVE ANSWER TO 2 SIGNIFICANT DIGITS)

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.

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now
