. The equations below give the x component of position for four objects as functions of time: Object 1: x(ta, where a5m Object 2: X(t) bt + c, where b 4-and C ::-1rn . Object 3: x(t) = eẹ+ft,where e=+5sn and f--g2 Object 4: x(t)gt2 h, where g-3and h +12m . a. b. c. Which objects have a velocity that changes with time? Which object is at the origin at the earliest instant, and what is that instant? For the object found in part b, what is its velocity 1 s after it is at the origin?
