this graph shows the acceleration of particles a and b. the two lines intersect each other at point o. what is the acceleration of particles a and particle b at point o?
it is 0.2 m/s2 for particle a and 0.05 m/s2 for particle b.
it is 0.65 m/s2 for both particles.
it is 0.68 m/s2 for both particles.
it is 2 m/s2 for particle a and 0.50 m/s2 for particle b.

D.  

It is -2 m/s2 for particle A and -0.50 m/s2 for particle B.

CORRECT FOR PLATO

an enlarged virtual image

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.
