Answer:
An object's acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant - if its direction changes.

Answer:
The acceleration of the rattlesnake, a = 126 m/s²
Explanation:
Given,
The initial velocity of the rattlesnake, u = 1.0 m/s
The final velocity of the rattlesnake, v = 20.0 m/s
The time duration to reach the final velocity, t = 0.15 s
The acceleration of a body defined as the rate of change of velocity by time, or simply the difference of final velocity and initial velocity by time.
The formula for acceleration is
a = (v-u)/t m/s²
Substituting the values in the above equation
a = (20 - 1.0 ) / 0.15
= 126 m/s²
Hence, the acceleration of the rattlesnake is, a = 126 m/s²
