Question

help! Answer the following question ​

Answer 1

b. 6m

c. To find average speed.

*Slope of D-T graph gives us "Speed"*

slope= d2-d1 / t2-t1

so, let's take d2= 4m, d1 =2m, t2= 8s and t1 = 4s

4-2 / 8-4

2/4

= 1/2 = 0.5m/s

there is two speed because the distance changing

d. Non-uniform motion
