Ответ:
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
