Accepted Answer

The speed of the lorry 4 seconds later, given it was moving with uniform acceleration of 1.5 m/s² is 12 m/sHow do I determine the final speed of the lorry?We'll begin by listing out the various parameters obtained from the question. This is shown below:Acceleration (a) = 1.5 m/s²Initial speed (u) = 6 m/sTime (t) = 4 secondsFinal speed (v) =?The final speed of the lorry can be obtained as follow:a = (v - u) / t1.5 = (v - 6) / 4Cross multiply v - 6 = 1.5 × 4v - 6 = 6Collect like termsv = 6 + 6v = 12 m/sThus, from the calculation made above, the final speed of the lorry is 12 m/sLearn more about velocity:https://brainly.com/question/26392384#SPJ1
