A worker drives a 0.500 kg spike into a rail tie with a 2.50 kg sledgeham-
Marianna [84]

Total internal energy increases by 1760 J

Step-by-step explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion.

It is calculated as

KE=\frac{1}{2}mv^2

where

m is the mass of the object

v is its speed

For the hammer in this problem:

m = 2.50 kg

v = 65.0 m/s

So its kinetic energy is

KE=\frac{1}{2}(2.50)(65)^2=5281 J

Then the problem says that 1/3 of the hammer's kinetic energy is converted into internal energy: therefore, the total internal energy increases by

\frac{1}{3}KE=\frac{1}{3}(5281)=1760 J

The Parsons have a balance of $3,664.47 in their check register. On their bank statement, the balance on the account is $2,346.8
Lapatulllka [165]
$2,346.89 + $500 + $1,456.81 = $4,303.70

$4,303.70 - $324.56 - $25.50 - $78.92 - $30.25 - $60 - $60 - $60 = $3,664.47

$3,664.47 is exactly what they have in their checkbook.

A train is leaving in 11 minutes and you are one mile from the station. Assuming you can walk at 4mph and run at 8mph, how much
ddd [48]

7 minutes is the time can you afford to walk

<em><u>Solution:</u></em>

Given that, train is leaving in 11 minutes and you are one mile from the station

Let "x" represent how much time can you afford to walk

Then, (11 - x) is the time you run

You can walk at 4mph and run at 8mph

<em><u>Convert to miles per minute</u></em>

1 hour = 60 minutes

4\ mph = 4 \times \frac{1}{60} \text{ miles per minute } = \frac{1}{15} \text{ miles per minute }\\\\8\ mph = 8 \times \frac{1}{60}\ \text{ miles per minute } = \frac{2}{15} \text{ miles per minute }

We know that,

Distance = speed \times time

Given that, you are one mile from the station

Therefore,

1 mile = distance walk + distance run

1 = x \times \frac{1}{15} + (11-x) \times \frac{2}{15}\\\\1 = \frac{1}{15}(x + 2(11-x))\\\\1 = \frac{1}{15}(x + 22 - 2x)\\\\x + 22 - 2x = 15\\\\x = 22 - 15\\\\x = 7

Thus, 7 minutes is the time can you afford to walk
