Three forces acting on an object are given by F1 = (−1.85î + 6.85ĵ) N, F2 = (4.85î − 2.35ĵ) N, and F3 = (−42.5î) N. The object experiences an acceleration of magnitude 4.00 m/s2.what is the direction of acceleration?

your answer is, orbit around the nucleus

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.
