Question

Cheetah the fastest of all land animals over a short distance accelerates from rest to 26 metres square per second assuming that the acceleration is constant find the average speed .

Answer 1

Average speed = Distance covered /Time taken

S= ut +1/2 at^2

Distance = 0*1+1/2*26*1^2

S = 13

Average speed = 13/1 = 13metre/ second

Hope it helps you.

Answer 2

Answer:

Average speed = Disctance Coverered/ Time taken

S= ut+ 1/2 at^2

Distance = 0*1+ 1/2*26*1^2

S= 13

Average Speed= 13/1= 13 metre/second
