Question

A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?

a) 1. 2.14 m/s²
b) 2. 4.29 m/s²
c) 3. 5.00 m/s²
d) 4. 60.0 m/s²

Answer 1

The acceleration of the cheetah is 4.29 m/s².

Step-by-step explanation:

To calculate the acceleration of the cheetah, we can use the formula:

acceleration = (final velocity - initial velocity) / time

Given that the cheetah accelerates from rest (initial velocity = 0 m/s) to a speed of 30.0 m/s in 7.00 s, we can substitute the values into the formula:

acceleration = (30.0 m/s - 0 m/s) / 7.00 s = 4.29 m/s²

Therefore, the acceleration of the cheetah is 4.29 m/s².
