Given:

1 mile = 5280 feet

1 meter = 3.3 feet

convert 60 miles per hour to meters per second

60 miles to meters

60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3

                 1 mile    3.3ft

= 96,000 meters

1 hour to seconds

1 hour x 60 minutes x 60 seconds =   1 * 60 * 60sec = 3600 seconds

               1 hour            1 minute

unit rate: meters per second

96000 meters ÷ 3600 seconds = 26 2400/3600

simplify 26 2400/3600 ⇒ 26 2/3 meters per second

2400 ÷ 1200 = 2

3600 ÷ 1200 = 3

A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it
natima [27]

Answer:

h = 61.25 m

Step-by-step explanation:

It is given that,

The initial velocity of the ball, v = 60 m/s

It is thrown from a height of 5 feet, h_o=5\ ft

We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :

h=-16t^2+vt+h_0

Putting all the values,

h=-16t^2+60t+5 .....(1)

For maximum height, put

\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s

Put t = 1.875 in equation (1)

h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m

So, the maximum height reached by the ball is 61.25 m.

The (greatest, least) of the common factors of 2 or more numbers is the (greatest, least) common factor of the numbers.
Liula [17]

Answer:

The greatest of the common factors of 2 or more numbers is the greatest common factor of the numbers.

Step-by-step explanation:

As we know that

The greatest common factor of two or more whole numbers is the largest whole number that divides evenly into each of the numbers.

Thus, the greatest of the common factors of 2 or more numbers is the greatest common factor of the numbers.

For example, lets find the greatest common factor of 36 and 54.

The possible factors of 36 are:

                                                   1, 2, 3, 4, 6, 9, 12, 18, and 36.

The possible factors of 54 are:

                                                   1, 2, 3, 6, 9, 18, 27, and 54.

The common factors of 36 and 54 are:

                                                   1, 2, 3, 6, 9, 18

So, from the common factors, it is easy to figure out that 18 is the greatest common factor.
