Adisk 8.06 cm in radius rotates at a constant rate of 1 300 rev/min about its central axis. (a) determine its angular speed. 136.1 correct: your answer is correct. rad/s (b) determine the tangential speed at a point 2.92 cm from its center. 3.97 correct: your answer is correct. m/s (c) determine the radial acceleration of a point on the rim. magnitude 1.49 correct: your answer is correct. km/s2 direction correct: your answer is correct. (d) determine the total distance a point on the rim moves in 1.94 s. m need ? read it master it

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.
