Villarreal · Answer 1

acceleration = (final velocity - initial velocity) / total time taken

initial velocity of cheetah = 16.7 m/s

final velocity of cheetah = 26.4 m/s

time taken to change speed = 5 s

acceleration = (final velocity - initial velocity) / total time taken

so acceleration = (26.4 - 16.7) / 5

acceleration = 9.7/5 = 1.94

the average acceleration of the cheetah over this period is 1.94 m/s²
