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 of the Cheetah

Answer 1

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

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= 13m/s
