Problem 1- The race car stars from rest at s = 0 and travels along a straight road. Its v-t graph is obtained as shown. The flat part of the graph is caused by shifting gears. Determine the acceleration, velocity, and position, i.e., a(t), v(t), s(t), of the race car as functions of time between 0 to 8 seconds. Problem 2- A particle moves a long a straight line. It starts with an initial velocity of 2 m/s with a constant acceleration of 4 m/s2. Once its velocity reaches 6 m/s, it decelerates at a = - 1 .5v1/2 m/s2 until it stops. Determine how far the particle has traveled during the entire process, and the total time of travel.

#### Complete the design of the link

a link in a mechanism is to be subjected to a tensile force that varies from 3500 to 500 N in cyclical fashion a the mechanism runs. It has been decided to use AISI 1040 col

#### Defining points and vectors of a parametric cubic curve

Find the equation of a Hermite cubic spline that passes through points (1, 1) and (3, 2) and whose tangent vectors are as follows: Sketch the curve and the blending functions

#### Compute the modulus of elasticity for the nonporous material

The modulus of elasticity for a ceramic material having 5 vol% porosity is 296 GPa (43x10^6 psi). (a) Compute the modulus of elasticity for the nonporous material. (b) At what

#### Neglect kinetic-potential energy changes-compressor power

Air is compressed at steady state from 100 kPa, 300 K, to 600 kPa, 440 K with a mass flow rate of 4 kg/s. Heat transfer occurs at a rate of 42.3 kJ/kg of air flowing to coolin

#### What is the energy density of the energy

How does this compare with the energy density (mc2) of particulate matter in the Universe which amounts to an average of 0.2 protons (mostly in hydrogen atoms) per cubic meter

#### Calculate the degree of polymerization

Explain why low-density polyethylene is good to make grocery bags, however, super high molecular weight polyethylene must be used where strength and very high wear resistanc

#### Determine the actual exit temperature for the compressor

A given mass flow rate (.17 kg/min) of an ideal gas flows through an adiabatic compressor operating at steady state. The compressor has an adiabatic efficiency of N(%) = 87.5.

#### Minimum power input needed to effect the soldering

Two long copper rods of diameter D = 10 mm are sol- dered together end to end, with solder having a melt- ing point of 650°C. The rods are in air at 25°C with a convection c
