HELP DUE AT 11!! Two objects are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. How much time (in s) does it take object m1 to hit the floor after being released? How would your answer to part (a) change if the mass of the pulley were neglected? (Enter the time, in seconds, it takes object m1 to hit the floor if the mass of the pulley were neglected.) The masses of the objects are m1 = 16.0 kg and m2 = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.100 m. Object m2 is initially on the floor, and object m1 is initially 4.80 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the rope is small enough to be ignored, and the rope does not slip on the pulley, nor does it stretch.

it was given as a lesson and guide for prayer.

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.
