Good Day

Problem:

Akieya is playing with a ball on top of a building but the ball fell and hits the squad after 1.9 second.What is the final velocity of the ball just before it hits the ground? How tall is the building?

Given Data:

a (acceleration) = 9.8 m/s²

t (time)  =  1.9 s

Vi (initial velocity) = 0 m/s

Vf (final velocity) = ? unknown

Solution:

We can use the formula, a = (Vf - Vi)/t

To find Vf, Vf = at + Vi

Vf = at + Vi

    = 9.8 m/s² × 1.9 s  + 0 m/s

    = 18.62 m/s + 0 m/s

    = 18.62 m/s

Answer:

Final velocity 18.62 m/s

What Is The Length Of The Side Of An Equilateral Triangle If Its Altitude Is 18 Cm?

What is the length of the side of an equilateral triangle if its altitude is 18 cm?   Answer: The length of the side of the equilateral triangle is 12√3  cm. Please click the image below to view my illustration and the complete solution. Step-by-step explanation: The altitude of an equilateral triangle (60°-60°-60°) divides it into two congruent 30°-60°-90° special right triangle. The new triangle formed has   a short (opposite the 30°), longer leg (opposite the 60°) and the hypotenuse (opposite the 90°) . The hypotenuse is the length of the original equilateral triangle. The theorem of 30°-60°-90° special right triangle states that the hypotenuse is twice the shorter leg and the longer leg is the product of shorter leg and √3. The longer leg is also half the product of the hypotenuse and √3. The altitude of the original equilateral triangle is also the longer leg of the new special triangle formed, while the hypotenuse is the side of the original equilateral triangle. Fi...

Variation Problems - Please Solve These For Me. I Need To Pass An Exam!, Exercise 16, 1.\Tthe Force (F) Exerted By An Object Varies Directly As Its Ma

VARIATION PROBLEMS - Please solve these for me. I need to pass an Exam! EXERCISE 16 1. The force (F) exerted by an object varies directly as its mass (m). If the force is 20 dynes when the mass is 440 kg., find the force when the mass is 1100 kg. 2. Hooke's Law states that the distance (d) that a spring is stretched varies directly as the weight (w) on the end of the spring. If the distance is 48 cm. when the weight is 120 gms., find the weight when the distance is 72 cm. 3. The amount of garbage varies directly as the number of people. If town A (population 50,000) produces 24 tons of garbage in a certain period, how much garbage would town B (population 2 million) produce in the same time period. 4. The amount of paper that is recycled varies directly as the acres of land which are saved from logging. If 5 tons of paper is recycled, 120 acres of trees are saved. How many tons of recycled paper are needed to save 300 acres of trees? 5. Time varies inversely as spe...
