The standard height of a goal post in American football is 3.3 m high. A)Suppose Cimaglia kicks the ball at an angle of 39 degrees, what must be the minimum speed with which he must kick the ball to clear the goal post if he is kicking from 35 yards away? (Report your answer in ft/s.) *This is a hard problem but hang in there!(include units with answer)B)If he kicks the ball with the speed you calculated in part A, at the same angle and distance, what will be the speed of ball (in ft/s) as it passes over the goal post?(include units with answer)

the inner core.

good luck: )

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.
