A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet

Complete Question

A juggler tosses a bowling pin in the air with an initial velocity of 18 ft per second. It leaves his hand when it is five feet from the ground and he catches it when it is four feet from the ground,How long is the ball in the air?

Answer:

$t\approx 0.1s$

Step-by-step explanation:

From the question we are told that

Initial velocity $V_0= 18 ft/s$

Initial Height $h_1=5feet$

Final Height $h_2=4feet$

Generally the Newtons equation for motion is mathematically given by

$V^2 = U^2 + 2as$

Where

$s=h_2-h_1\\s=4-5\\s=-1ft$

And

$a=g=>9.81\\a=32.2ft/s^2$

Therefore

$V^2 = (18)^2 + 2(-32.2)(-1)$

$V^2 = 388.4$

$V =19.70786645\\V=19.71ft/s$

Generally the equation for Time is mathematically Given as

$t=\frac{V-U}{a}$

$t=\frac{19.71-18}{32.2}$

$t=0.05310559006$

$t\approx 0.1s$

Therefore the time spent on air by the ball is

$t=0.05310559006s$

A utility company measures gas consumption by the hundred cubic feet, CCF. The company has a three-step rate schedule for gas cu

sweet [91]

Answer:

$\$(4.65 + 0.55g)$

Step-by-step explanation:

Let the number of hundred CCF of gas consumed by the customer =g

$\text{When } 0 < g \leq 3\\ \text{Cost =} \$5\\\\\text{When } 3$

Therefore, when the hundred cubic feet, CCF of gas consumed is more than 9, the consumer pays for the first 9 and then pays for any subsequent CCF of gas at a rate of $0.55 per CCF

$\text{When g}>9 : \text{Cost =} 9.60+0.55(x-9)$
