A man and his bike are 95 kg. His instantaneous speed at one point is 14m/s. The next time his speed is checked he is going 28m/s. If the second speed was taken 7 seconds later, what force must the man have man and his bike are 95 kg. His instantaneous speed at one point is 14m/s. The next time his speed is checked he is going 28m/s. If the second speed was taken 7 seconds later, what force must the man have given his bike to change the speed? What was the bicyclist’s final momentum? e has given his bike to change the speed? What was the bicyclist’s final momentum?

choosing tennis and golf balls is your inde choice.

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.
