Acart is given an initial velocity of 2 m/s and experiences a constant acceleration of 2 m/s2. what is the magnitude of the cart's displacement during the first 6 s of its motion?

48 m

Explanation:

Since we are dealing with constant acceleration, we can use the following equations:

(1)

(2)

Where:

is the cart’s final velocity

is the cart’s initial velocity

is the cart's acceleration

is the time

is the cart's displacement

So, firstly we have to find from (1):

(3)

(4)

Isolating from (2) and substituting (4):

(5)

(6)

Finally:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

no
