Question

Use this graph to answer.

Calculate the turtle’s velocity during the following time intervals: 0-2

Answer 1

10 m/s

Step-by-step explanation:

Find the displacement.

xf - xi = d

0 - (-10) = 10 m

Find the acceleration.

d = 1/2at^2

10 = 1/2a(2)^2

10 = 1/2a(4)

10 = 2a

a = 5 m/s^2

Find the velocity.

v = at

v = 5(2)

v = 10 m/s
