A 100 kg object and a 50 kg object are dropped from two different cranes. The 100 kg object is 50 m high and the 50 kg object is 10 m high when they are both released at the same time. Which of the following statements are true about the two objects ? ( Assume no air resistance)

mistakes are ok

a electromagnetic waves

f is prop to m1xm2 double m1 double force

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.
