Finally, you are ready to answer the main question. Cheetahs, the fastest of the great cats, can reach 50.0 miles/hour in 2.22 starting from rest. Assuming that they have constant acceleration throughout that time, find their acceleration in meters per second squared.

Acceleration = 10.06 m/s²

Explanation:

1 mile = 1.6093km

1609.3m = 1 mile

1 m = mile

50.0 miles/hour = m/s

                          = 22.35m/s

from equation

S = Ut + 1/2 at²

v = U + at

22.35 = 0 + a * 2.22

a = 22.35 ÷ 2.22

= 10.06 m/s²

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

snell's law

refractve index = sin incidence / sin refraction
