Question

Define Average speed. An object moves with uniform speed of 10 m/s for 5s and then with a uniform speed of 5 m/s for 10s. Find its average speed.

Answer 1

Answer:

hope it helps you

Explanation:

At first , 

10m/s for 5sec 

 s= vt 

   = 10* 5

    = 50 m

in second , 

  5m/s for 10 sec

s= vt 

  = 5*10 

  = 50 m 

totak distance = 50 +50 

                      = 100 m 

total time = 10 +5 

               = 15 sec 

average velocity = total distance / total time taken 

                          = 100/ 15

                           =6.66 m/s
