Answer 1

:

vi = 0 m/s

vf = 108 km/h

t = 10 s

a = ?

d = ?

vf = (108 km/h) (1000 m) / (1 km) (1 h) / (3600 s) = 30 m/s

́.

a = (vf - vi)/t

a = (30 m/s - 0 m/s)/10s

a = (30 m/s + 0 m/s)/2 * 10s

a = 3 m/s₂

.

d = (vf vi)/2 * t

d = (30 m/s + 0 m/s)/2 * 10s

d = (30 m/s)/2 * 10s

d = 15 m * 10

d = 150 m
