Assume that at t1=0.25s the velocity of the object is v1=5.0cm/s. find the following velocities of the object: v0 at t0=0.0s, v2 at t2=0.50s , v3 at t3=0.75s, and v4 at t4=1.0s.

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
