# A car with an initial velocity of 20m/s also accelerates at 1m/s2. find its displacement after the first 10seconds in m.

We use the formula: X = VoT + (1/2)AT^2 --> X = (20 m/s)(10 s) + (1/2)(1 m/s^2)(10 s)^2 = 250 m.

d=Vot + at²/2

=(20m/s)(10s) + (1m/s²)(10s)²/2

= 200 m + 100m/2

= 200 m + 50m

d = 250 m

Then it traveled 250 meters in 10 seconds.
