Un bate de beisbol ejerce una fuerza promedio de 50n sobre una pelota durante 0.40s. ¿Qué impulso recibió la pelota? tras ser bateada una pelota de beisbol de 0.11 kg se separa de bate con una rapidez horizontal de 36m/s si el bate esta en contacto con la pelota por 0.5 s ¿Cuál es el valor de la fuerza horizontal promedio que ejerce el bate en la pelota?

increase masses, decrease separation

it is a negative acceleration

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.
