Question

Find the average speed in time interval t=2sec to t=10sec​

Answer 1

As we know that speed=distance/time

Or, s=10ms^-1/10ms^-1

or, s=1ms^-1

So, it will be option (a)1ms^-1

Answer 2

Answer:

we know that

Average speed = total distance / total time taken

a).1 m/s

then,

1= d/2+10

1= d/12

d = 1×12

d=12 m

b).0.5m/ s

0.5= d /12

d= 0.5×12

d=6m
