Question

1. An object travels 16 m in 4 s and then
another 16 m in 2 s. What is the average
speed of the object? Ans. 5.33 ms'​

Answer 1

Answer:-

5.33m/s

Given :-

16 m in 4s.

16m in 2s.

To find:-

The average speed of the object.

Solution:-

Average speed :- It is the ratio of total distance covered by total time taken by a body during his journey is known as average speed.

From definition,

$Average\: speed = \dfrac{Total \:distance\:travelled} {Total \:time\: taken}$

Now,

$Av_s = \dfrac{16 +16}{4+2}$

$Av_s = \dfrac{32}{6}$

$Av_s = 5.33 m/s$

hence,average speed will be = 5.33m/s
