A car traveling initially at 7.35 m/s acceler-
ates at the rate of 0.824 m/s² for 2.09 s.
What is its velocity at the end of the accel-
eration?
Answer in units of m/s.

Answer:

[tex]v_f=9,07~m/s[/tex]

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes uniformly in time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

[tex]v_f=v_o+at[/tex]

The car initially travels at vo=7.35 m/s and accelerates at a rate of [tex]a=0.824~m/s^2[/tex] during t=2.09 s.

The final velocity is:

[tex]v_f=7.35+0.824*2.09[/tex]

[tex]\mathbf{v_f=9,07~m/s}[/tex]
