Awoman with mass m is standing on a platform and holding onto a light rope attached to a hook in the ceiling. a second rope, also attached to the hook, is being held by a man with larger mass m on a second platform. the ropes are the same length, and the ropes are initially horizontal. the two people start from rest and swing toward each other. they meet at the lowest point of their swings, and grab onto one another, swinging upward until the ropes make an angle of 32.8° with the vertical. find the value of the ratio m m .

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

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.
