Question

1.Observe the figure showing the distances travelled by a car during different time

intervals

0 s 4 s 8 s 12 s 16 s 20 s

A B C D E F

0 40m 60m 100m 120m 200m

a) Analyse the figure and complete the table

Distance travelled Time speed

A → B

B → C

C → D

D → E

E → F

b) Whether the movement of car is in uniform motion or in non uniform motion?

c) Whether the speed of car is in uniform speed or in non uniform speed?

d) Calculate average speed of the car?
​

Answer 1

Answer:

b. momentum of car is in non uniform motion because unequal distances in equal interval of time.

c. the speed of car is a in not uniform because an equal distance travelled in equal interval of time

d average speed of the car is total distance travelled by total time taken

Vavg= 200/20=10m/s
