Explain and give an example.arrow_forwardSuppose you drop a rock into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. (a) Neglecting the time required for sound to travel up the well, calculate the distance to the water if the sound returns in 2.0000 s. (b) Now calculate the distance taking into account the time for sound to travel up the well. The speed of sound is 332.00 m/s in this well.arrow_forwardDo highway speed limit signs refer to average speeds or to instantaneous speeds? Explain.arrow_forward

Unfortunately, the crumbs are eaten by birds, and the children cannot find their way home. In this modern-day problem, the children use a device that releases a drop of food dye once per minute. As long as it does not rain, they can find their way home. As an extra bonus, they make a motion diagram as shown in Figure P2.6. a. Describe the motion of the children in words. b. Using the coordinate system in Figure P2.6, make a position-versus-time graph. Note any ambiguities you encounter. c. Is your position-versus-time graph consistent with your description in part (a)?
