A small 22 kilogram canoe is floating downriver at a speed of 1 m/s. What is the canoe's kinetic energy?

1 answer:

7 0

Kinetic energy is expressed through the formula Ke=1/2mv^2, where Ke is measured in Joules (kg•m^2/s^2). For this problem, just plug in the given values:

Ke=1/2mv^2
Ke=1/2(22kg)(1m/s)^2
Ke=1/2(22)(1)
Ke=11

This canoe, with a weight of 22 kg and a speed of 1 m/s, has a kinetic energy equal to 11 Joules.

Steven wants to increase the number of books he reads per year. He currently reads 2 books a year. He wants to triple the number

Sladkaya [172]

Answer:

$B=2\times 3^n$

Step-by-step explanation:

<u>Exponential Growing </u>

Steven currently reads 2 books a year. He wants to triple the number of books read per year. The first year he should read

$2*3 = 6\ books$

By the second year, he should read

$2*3^2 = 18\ books$

By the third year, he should read

$2*3^3 = 54\ books$

We can clearly see there is a geometric progression of the number of books he should read for the year n. The general formula is, being B the number of books read at the year n

$\boxed{B=2\times 3^n}$

Answer:

Every angle of Square = 90°

diagonal bisects the angle in half.

=> angle FGI = 45°

=> 7x+3=45

=>7x=42

therefore, x=42/7=6
