Chapter 7, Problem 7.8P
Interpretation Introduction

(a)

Interpretation:

The speed of head of the hammer at which it must be travelling at the moment of impact to ring the bell is to be calculated.

Concept introduction:

The kinetic energy of the hammer is calculated by the formula,

Ek=12mhu2

The transfer of energy from hammer to the metal ball takes place when a pedal is hit hard by a hammer. The speed of metal ball can reduce if the friction between metal ball and surface of the pole is more.

Interpretation Introduction

(b)

Interpretation:

The three assumptions made to solve Part (a) and their impact on solution is to be stated.

Concept introduction:

The kinetic energy of the hammer is calculated by the formula,

Ek=12mhu2

The transfer of energy from hammer to the metal ball takes place when a pedal is hit hard by a hammer. The speed of metal ball can reduce if the friction between metal ball and surface of the pole is more.

On December 1, 1783, Jacque Charles became the first human to pilot a non-tethered hydrogen balloon. He flew the balloon for fifteen miles and stayed in the air for a total flight time of 45 minutes. The balloon was made of silk coated with a thin layer of natural rubber and had a diameter of 27 feet. He generated the hydrogen gas needed to lift the balloon by mixing a large amount of iron with aqueous sulfuric acid. If he used 1 x 103 lbs. of iron and excess sulfuric acid, how many liters of hydrogen gas were made? Fe(s) + H2SO4(aq) = FeSO4 (aq) + H2(g)
A rigid cylinder of gas shows a pressure of 500 torr at 215 K. The cylin- der is moved to a new storage site where the pressure within the cylinder is now measuring 800 torr.

A common unit of pressure is the Pascal, Pa, which is equivalent to Newton per meter squared (N/m2).  The common English unit for pressure is psi or pounds per square inch.  Convert 101.325 kPa to psi if 1 Newton is equivalent to 0.224808943 pounds.  Remember a squared value is a unit multiplied by itself (in2 = in x in).
