Answer:

a) (1) 12 m/s

(2) 18 seconds

(3) 198 metres

b) 2 m/s

Explanation:

a) (1) ****locate on the graph****

(2) if 2 small squares = 1 second

then (36/2 × 1) = 18 sec

(3) Dist= ?

Speed= 11 m/s

Time= 18 sec

then D=S×T

D=(18×11 )= 198 m

b) a = change in velocity /change in time

initial velocity = 11 m/s

final velocity. = 28 m/s ***graph***

initial time. = 28 sec ***graph***

final time. = 36 sec ***graph***

a= (11 - 28)/(28/36)

a= (-16/-8)

a= 2 m/s
