v =10 m/s , u = o and s = 4 cm = 0.04 m
V2 - u2 = 2as
(10)2 - (0)2 = 2 a (0.04)
- 100 = 0.08a
a = -100/0.08
a= -1250 m/s2

Snakes have four ways of moving around. Since they don't have legs they use their muscles and their scales to do the "walking". Snakes will push off of any bump or other surface, rocks, trees, etc., to get going. They move in a wavy motion.

A parallax error is the perceived shift in an object's position as it is viewed from different angles. The error is most easily noticed by looking at a nearby object with one eye closed, then looking at it through the other eye. The apparent motion of the object is the parallax shift, and it is responsible for a small, but noticeable, error common to optical equipment.
