The equation for acceleration a is: a=v/t, where v is velocity and t is time. From there we can calculate the velocity: v=at, at any time if we know acceleration. If acceleration a is constant then:

a=v₁/t₁=5/0.25=20 cm/s²

Now we can find all velocities for the object:

v₀=at₀=20*0=0 cm/s

v₂=at₂=20*0.5 = 10 cm/s

v₃=at₃=20*0.75=15 cm/s

v₄=at₄=20*1=20 cm/s
