URGENT PLEASE HELP. 1) A simple Atwood's machine uses a massless
pulley and two masses mi and m2. Starting
from rest. the speed of the two masses is
1.1 m/s at the end of 7.6 5. At that time, the kinetic energy of the system is 86J and each mass has moved a distance of 15.58m. Find the value of the heavier mass. The acceleration due to gravity is 9.81m/s^2. Answer in units of kg.

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

spare some change and give it to the poor

explanation:

plz : ((

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.
