The boys had 5 4 6 gallons of water to share throughout the day. James drank 1 1 3 5 6 1 2 gallons and Simon drank 2 3 gallon. H

Answer:

$1\frac{1}{3}$

Step-by-step explanation:

Total Volume of Water = $5\frac{4}{6}$

Volume drunk by James = $1\frac{1}{3}$

Volume drunk by Simon = $\frac{2}{3}$

Volume drunk by Matthew = $1\frac{1}{2}$

Volume drunk by Gilbert = $\frac{5}{6}$

Total Volume Drunk (i.e. The Sum) = $1\frac{1}{3} + \frac{2}{3} + 1\frac{1}{2} +\frac{5}{6}=\frac{13}{3}$

Volume of water Left = Total Volume of Water-Total Volume Drunk

= $5\frac{4}{6}-\frac{13}{3} =\frac{4}{3}=1\frac{1}{3}$

Determine the kinetic energy of a 100-kg roller coaster car that is moving with a speed of 20.0/ms.

rjkz [21]

Answer:

The kinetic energy is 20,000\ J

Step-by-step explanation:

The kinetic energy of a body is defined as:

$k = \frac{1}{2}ms ^ 2$

Where m is the mass of the roller coaster car

s is the speed and k is the kinetic energy

We know that $s = 20\ m/s$

$m = 100\ kg$

Then the kinetic energy of the roller coaster car is:

$k = \frac{1}{2}(100)(20) ^ 2\\\\k = 50(20) ^ 2\\\\k = 50 * 400\\\\k = 20,000\ J$
