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:

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb
