Ashopping cart given an initial velocity of 2.0 m/s undergoes a constant acceleration of 3.0 m/s2. what is the magnitude of the cart’s displacement after the first 4.0 s of its motion?

32 m

Explanation:

initial velocity (u) = 2 m/s

accceleration (a) = 3 m/s^{2}

time (t) = 4 s

What is the magnitude of the cart’s displacement (s) after the first 4.0 s of its motion?

from the equation of motion, displacement (s) =

where

inserting all required values into  (s) =          

(s) =

s = 8 + 24

s = 32 m

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

i don't understand. explain it clearly
