an object at rest starts accelerating if it travels 30 meters to end up going 10 m/s what was it’s acceleration

Respuesta :

First we have to calculate the time taken to travel the distance 30 m, is

[tex]t = \frac{distance}{velocity} = \frac{30 \ m}{10 \ m/s } =  3 \ s[/tex].

Now from equation of motion,

[tex]v = u + at[/tex]

Given, [tex]v = 10 \ m/s[/tex] .

As object starts from rest, so  u = 0.

Substituting these values in above equation, we get

 [tex]10 \ m/s = 0 + a \times 3 \ s \\\\ a = \frac{10}{3}  = 3.33 \ m/s^2[/tex].

Thus, the acceleration is [tex]3.33 \ m/s^2[/tex]
