Answer 1

Answer:

Brian list of the Samsung s named in the

Answer 2

Answer:

70 m

Explanation:

The area of the velocity time graph gives us the displacement

Because vt = s

The area above x - axis is +ve area

The area below x - axis is -ve area

The area of shape 1 = 1/2 × 2 × 20 = 20

The area of shape 2 = 20 × 2 = 40

The area of shape 3 = 1 × 20 = 20

The area of shape 4 = 1/2 × 20 × 1 = 10

The area of shape 5 =  - (1/2 × 40 × 1) = -20

The area of shape 5 is negative because it is below x - axis

Adding all these, we get,

20 + 40 + 20 + 10 -20 = 70 m
