The acceleration of the car,
Here, v is final velocity, u is initial velocity and t is time taken by the car.
Given 
,
and 
Therefore, from above equation
.
Here, negative sign shows deceleration of a car.
Thus the the magnitude of car acceleration is 
.
Answer:
v=-30 m/s
Explanation:
Using the equation:
v=u+at
v=?
u means initial velocity=0
a=-10 since it is going down we make the acceleration due to gravity negative
t=3
v=0+(-10)(3)
v=-30 m/s

The answer is (b) digestion.
A decomposition reaction is a process in which a single compound breaks into two or multiple elements or compounds. A best example is digestion where a large insoluble food molecules breakdowns into small water-soluble molecules so that they can be absorbed into the watery blood plasma.
