Answer 1

6)DATOS

A = 24m/seg2

T=10seg

D=360m

V•=??

FORMULA

V•= d/t- (a×t/2)

V•=360m/10seg - (24m/seg2 × 10seg/2)

V•=36m- 240m/seg/2

V•=36m - 120m/seg

V•= - 84m/seg

7)DATOS

V•=70m/seg

T=8seg

Vf=..??

FORMULA

a= V•/t

a= 70m/seg/8seg

a= 8.75m/seg2

Vf=V•+a×t

Vf=70seg + 8.75m/seg2 × 8seg

Vf=70seg + 70m/seg

Vf=140m/seg
