A car increases velocity from 30 misto 50 m/s in 4 seconds. Calculate the average acceleration of the car over this time

7.5 m/s2
0.3 m/s2
4.8 m/s2
0.6 m/s2

Respuesta :

Answer:

5 m/s^2

Explanation:

By definition of average acceleration,

[tex]a = {\Delta v \over \Delta t[/tex] Let's replace what we know, remembering that [tex]\Delta v = 50 - 30 = 20 m/s[/tex]

[tex]a= {{20 m/s} \over 4s} = 5 m/s^2[/tex]
