An atom is constrained to move along the horizontal axis only. At time t = 0.5 s, the atom is at x = 0.06 m. At time t = 2.8 s, the atom is at x = 0.46 m. What is the atom's average velocity?
If an archer shoots an arrow straight upward with an initial velocity of 160ft/sec from a height of 8 ft, then its height above ground in feet at time t in seconds is given by the function h(t)=-16t^2+160t+8. (a) what is the maximum height reached by the arrow?
In reaching her destination, a backpacker walks with an average velocity of 1.48 m/s, due west.
