Question

2.
A cheetah can accelerate from 0 to 90 km/h in 2.0 s
while a tiger required 4.5 s. The ratio of average
acceleration of cheetah to tiger is
​

Answer 1

Answer:

12.5/5.5

Explanation:

First convert into m/s ..

90km/h = 25 m/s

Avg acc (cheetah)= ∆v/∆t = 25-0/2= 12.5m/^2

Avg acc(tiger)= 25-0/4.5= 5.5 m/s^2

so now the ratio = 12.5/5.5
