Hobart works as a stock boy at the local grocery store. His manager, Jessica, put 84.6 kg worth of canned soup on a cart for Hobart to put on the shelf. Hobart accelerates at a rate of 0.76 m/sec2 as he pulls the cart from the back room to the soup aisle. How much force is he using to pull the cart? Type your calculation below.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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.
