First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.
Tell me if you need any clarification
PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.

Answer:
60
Step-by-step explanation:
Just use similar triangles.
12/10 = 72/x
Now solve for x.
x = 72 * 10 / 12 = 60
Answer:
No. It is not an Exponential Equation.
Step-by-step explanation:
Given
By the Definition of Exponential Equation which states.
"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."
For Example:
All given below are said to be exponential equations.
which can be rewritten as
Now in the given equation 
it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation
3 kilograms because 1,000 grams is equal to 1 kilogram
