Question

11. A car, starting from rest, accelerates in a straight-line path at a constant rate of 2,5 m/s2 . How far will the car travel in 10 seconds?

(a) 180 m
(b) 30 m
(c) 125 m
(d) 4.8 m​

Answer 1

Answer: 125 m

Step-by-step explanation:

`V_(i)` = 0

`V_(f)` = no se conoce

a = 2,5
`(m)/(s^(2) )`

t = 10 s.

d= x no los piden

Formula:

`d=V_(i) .t + (a.t^(2) )/(2)`

Remplazamos:

`d=0.(10) + (2,5.10^(2) )/(2)` = 0 +
`(2,5.(100))/(2)` = 2,5.(50) = 125 m
