X + 3 because in math two negatives equal a positive
Answer:
1.a. it takes him 0.5 seconds to reach his max height.
.b. The highest point that he reached is 484 feet.
-16×(0,5)^2+16×(0,5)+480=484
Answer: 12 inches to 1 foot.
Step-by-step explanation: Well, there is 12 inches in 1 foot, so the last one if I'm not mistaken. knowing this, 100 / 12 = 8.33
100 inches per minute converts to 8.33 feet per minute.
Answer with Step-by-step explanation:
Let a mass weighing 16 pounds stretches a spring feet.
Mass=
Mass=
Mass,m= Slug
By hook's law
A damping force is numerically equal to 1/2 the instantaneous velocity
Equation of motion :
Using this equation
Auxillary equation
Complementary function
To find the particular solution using undetermined coefficient method
This solution satisfied the equation therefore, substitute the values in the differential equation
Comparing on both sides
Adding both equation then, we get
Substitute the value of B in any equation
Particular solution,
Now, the general solution
From initial condition
x(0)=2 ft
x'(0)=0
Substitute the values t=0 and x(0)=2
Substitute x'(0)=0
Substitute the values then we get
The area is 20 cm²
Explanation:
0.05 m as centimeters is 5 cm so the formula to find the area of a triangle is base times height divided by two so we take the base eight times the Height five and divided by by two to get 20 cm²
