Messi mengendarai becak yang kondisi awalnya diam. Jika Messi mengendarai becak selama 20 s dan percepatan 10 m/s²

v0 = 0 m/s

t = 20 s

a = 10 m/s²

S0 = 2 m

dit :

a.t = ..??

b.st = …??

berarti

a = (vt – v0)/t

vt – v0 = a.t

vt – 0 = 10.2

vt = 20 m/s

b.

St = S0 + 1/2 x a x t²

St = 20+ 1/2 x 10 x 20²

St = 20+ 2000

St = 2020 m

St = 2,02 km

Penjelasan:

A. Vt=Vo+at

=0+10×20

=200 m/s

B. St=So+1/2×a×t^2

=20+(1/2×10×20^2)

=20+2000

. =2020 m
