an 12 n force is applied to a 1 kg object. what is the magnitude of the object's acceleration?
a. 0.083 m/s²
b. 11 m/s²
c. 12 m/s²
d. 13 m/s²

The magnitude of the acceleration is 12 m/s^2

Explanation:

In the image attached, we can see a free body diagram. The total force acting over the body is 12 N, and the mass of the object is 1 kg, therefore by Newton's second law, we have one equation with one unknown value (the 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.
