With an average acceleration of – 1.2 m/s”, how long will it take a cyclist to bring a bicycle with an initial speed of 6.5 m/s to a complete stop?

if x = 1, then the answer is 3.5

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
