At t = 0, an object moving along the x-axis, passes a position x0 = 20 m (from fixed reference origin) with velocity given by v(t) =3t^2−25m/s, with time t in seconds. What is (c) the position coordinate of this object at time t = 4 s, and (d) the magnitude of the acceleration of the object after t = 0?
At t = 0, an object moving along the x-axis, passes a position x0 = 20 m (from fixed reference origin) with velocity given by v(t) =3t^2−25m/s, with time t in seconds. What is (a) The average velocity of the object from t = 1 s to t = 4 (b) The average acceleration of the particle from t = 1 s to t = 4?
