A plane travelling at 52 m/s begins to accelerate at 2. 8 m/s Squared ? What is the planes velocity after 5 s?

Sagot :

We are given the following information

Initial velocity of plane = 52 m/s

Acceleration of plane = 2.8 m/s^2

Time = 5 s

We are asked to find the final velocity of the plane.

Recall the first equation of motion given by

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

Let us substitute the given values into the above equation

[tex]\begin{gathered} v_f=v_i+at \\ v_f=52_{}+2.8\cdot5 \\ v_f=52_{}+14 \\ v_f=66\; \frac{m}{s} \end{gathered}[/tex]

Therefore, the plane's velocity after 5 s is 66 m/s
