Answer:
a) (1) 12 m/s
(2) 18 seconds
(3) 198 metres
b) 2 m/s
Step-by-step 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
