Question

A toy car moves 8 cm towards east then turns at right angle towards north and covers 6 cm distance. If this entire journey is completed in 10 s, then compute the average speed and average velocity of the toy car.

Answer 1

Answer:

Speed=1.4m/sec

Explanation:

speed=distance/time

Answer 2

Answer:

➡️time taken = 10 s

➡️ total distance travelled = (6+8)cm = 14 cm =0.14 m

➡️ displacement = distance between final position and initial position = √6^2 + 8^2 = 10 cm = 0.1 m

so, average speed = total distance/total time taken = 0.14/10

= 0.014 m/s

average velocity = displacement/ total time taken = 0.1/10 = 0.01 m/s

hence, average velocity of toy car is 0.01 m/s and average speed of toy car is 0.014 m/s
