A collection of flash strobe photographs was taken every second of a set of spheres moving from left to right. The diagram shows the location of each sphere when the photo was taken. All the positions are in meters. Use the diagram to answer the following questions. A. Which digram(s) show acceleration? Explain how you know?

B. Which diagrams show deceleration? How do you know?

C. Which diagrams show constant velocity? How do you know?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
