How long would it take a rolling can to accelerate from 16 m/s to 24 m/s with an acceleration of 4m/s2? (Which equation would I use?)

answer is option 3

Explanation:

because you need to find out time

Option 3

Explanation:

Since we are solving for time, the time should be by itself on a side.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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.
