A basketball player shoots toward a basket 5.3 m away and 3.0 m above the floor. If the ball is released 1.9 m above the floor a
Snezhnost [94]

Answer:

Vi = 8.28 m/s

Explanation:

This problem is related to the projectile motion.

As we know there are two components of motion associated with this, the horizontal component and vertical component.

The horizontal distance covered by the ball is

Vx*t = x

Vx*t = 5.3

Vx = 5.3/t  eq. 1

Also we know that

Vx = Vicos(60)

Vx = Vi*0.5  eq. 2

equate eq. 1 and eq. 2

5.3/t = Vi*0.5

5.3/0.5 = Vi*t

Vi*t = 10.6  eq. 3

The vertical distance is

Vy = y1 + Vyi*t - 0.5gt²

also we know that

Vyi = Visin(60)

Vyi = Vi*0.866

It is given that V1 = 1.9 m and and Vy = 3 m is the vertical distance

3 = 1.9 + Vi*0.866*t - 0.5gt²

3 = 1.9 + Vi*0.866*t - 0.5(9.8)t²

3 = 1.9 + 0.866(Vi*t) - 0.5(9.8)t²

3 = 1.9 + 0.866(Vi*t) - 0.5(9.8)t²

1.1 = 0.866(Vi*t) - 4.9t²

0.866(Vi*t) = 4.9t² + 1.1

substitute Vi*t = 10.6 in above equation

0.866(10.6) = 4.9t² + 1.1

9.18 = 4.9t² + 1.1

4.9t² = 8.08

t² = 8.08/4.9

t² = 1.648

t = 1.28 sec

Finally, initial speed can be found by substituting the value of t into eq. 3

Vi*t = 10.6

Vi = 10.6/t

Vi = 10.6/1.28

Vi = 8.28 m/s

Anuta_ua [19.1K]
Energy = mc (delta T) where m is the mass in kg, c is the specific heat capacity, and delta T is the change in temperature.

450 = (45x10^-3)c (78-22)

450 = (0.045)c (56)

c = 178.57 J/kgK

Place each description in the correct category.
Kay [80]

Answer:

Elements- made of one type of atom

Can not be broken down

Compounds

Represented by formulas

Can be chemically broken down

Made of two or more types of atoms

Explanation:

An element is a chemical substance which cannot be further broken down into other chemical substances. An element is composed of only one type of atom. Examples of elements include, sodium, magnesium, gold, silver etc.

Compounds are formed when one or more elements combine in a definite ratio. Compounds are represented by chemical formulas which show the number of combining atoms e.g CaCO3, HF, etc. Some compounds can be broken down chemically.
