Question

A model rocket is launched from the ground.

The graph at the right shows the height of the rocket at various times.

a. Find the rates of change between points A and B and between points B and C.



b. Which rate of change is greater? What does this tell you about the motion of the rocket?

Answer 1

A)
rate of change from A to B = 48-0 / 1-0 = 48/1 = 48 ( feet per second)

rate of change from B to C = 64 -48 / 2-1 = 16 /1 = 16 ( feet per second)

B) the rate from A to B is greater. This tells me gravity starting acting on the rocket and started slowing it down
