Question

AYUDA
A car starts from rest and accelerates uniformly over a time of 5,21 seconds for a distance of
110 m.
Determine the acceleration of the car.​​

Answer 1

Respuesta:

a = 8,106 m/s²

Explicación:

• Data:

Vo = 0 m/s (rest)

t = 5,21 s (time)

d = 110m (distance)

a = ? (aceleration)

• Resolution:

We use:

d = Vo.t + 1/2.a.t² substituting values,  if Vo = 0 m/s

110 m = (0 m/s)x5,21s  + (1/2)xax(5,21s)²

110m = 0 + 13,57.a

a = 110 / 13.57

a = 8,106 m/s²
