Aperson wax walk at 1m/sand then accelerate at 2 m/s^2 for 2 seconds
after theses two seconds the person is moving at m/s and has traveled

The person is moving at 5 meters per second (m/s)

The person has traveled 6 meters

Explanation:

This is an example of accelerated motion (motion under acceleration), and therefore we need to use the appropriate equations of motion for it.

The information we have includes:

1) The initial velocity () of the person = 1 m/s

2) The person's acceleration () = 2

3) The time (t) the person moves under accelerated motion = 2 seconds

The following two equations are those to find the final velocity under accelerated motion, and the distance covered (from initial position to final position ) under accelerated motion:

We use the first equation and the information given, to find the speed of the person after 2 second under this motion:

We use the second formula to find the distance traveled by the person:

real, smaller and upside-down.   so the answer should be b.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
