Question
A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?
Step-by-Step Solution
Verified Answer
The acceleration of the cheetah is 4.28 m/s2.
1Determination of formula for acceleration of cheetah Given Data
The duration for acceleration is t = 7 s
The initial speed of cheetah is u = 0 m/s
The final speed of cheetah is v = 30 m/s
The acceleration of a particle is the variation in the velocity of the particle with time between different positions.
The acceleration of the cheetah is given as
v = u + at
Here, a is the acceleration of the cheetah.
2Determination of acceleration of cheetah
Substitute all the values in the above equation.
30 m/s = 0 m/s + a (7)s
a = 4.28 m/s2
Therefore, the acceleration of the cheetah is 4.28 m/s2.
