1. the head of a rattlesnake can accelerate 50.0 m/s in striking a victim. if a car could do

this as well, how long would it take for it to reach a speed of 24.6 m/s from rest?

0.492 s

Explanation:

We can use the following equation to solve this problem:

Where:

is the car’s final velocity

is the car’s initial velocity  (it starts from rest)

is the car's acceleration  

is the time we have to find

Isolating :

Finally:
