Answer 1

Answer:

Given,

d = 110 m t = 5.21 s v₁ = 0 m/s a = ??

d = v₁*t + 0.5*a*t²

110 m = (0 m/s)*(5.21 s)+ 0.5*(a)*(5.21 s)²

110 m = (13.57 s²)*a

a = (110 m)/(13.57 s²)

a = 8.10 m/ s²

========================================================

given,

a = -9.8 m t = 2.6 s vi = 0 m/s

d = vi*t + 0.5*a*t²

d = (0 m/s)*(2.60 s)+ 0.5*(-9.8 m/s²)*(2.60 s)²

d = -33.1 m

vf = vi + a*t

vf = 0 + (-9.8 m/s²)*(2.60 s)

vf = -25.5 m/s
