Thank you.arrow_forwardExplain this given Uniform of motion in your own words.arrow_forwardFor 4.95 seconds, a particle moves in a straight line according to the position function f(t) = (t³ + 1)(5 – t) – 5 where t is measured in seconds and f in feet. You can visualise this motion and verify many of your answers using a graph. First attempt all the problems by hand, and then graph the position function to verify your answers. a) What is the position of the particle at t = 0, t = 1, t = 2, t = 4.95? b) Find the velocity of the particle at time t.
