A cheetah runs at a steady velocity of 60 km/h (16.7 m/s). Over a period of 5.0s, the cheetah increases its pace to 95 km/h (26.4 m/s). What is the average acceleration of the cheetah over this period? must show work.

Respuesta :

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
