Methyl methacrylate was polymerized at a mass concentration of 200g dm^-3 in toluene using azobisisobutyronitrile as initiator at a mass concentration of 1.64 X 10^-2 g dm^-3 and a reaction temperature of 60 degree C. Calculate the initial rate of polymerization and the molar mass of the poly(methyl methacrylate) formed in the initial stages of the reaction given that the relevant rate coefficients at 60 degrees C are:

Initiator dissociation: k sub d= 8.5 X 10 ^-6 reciproical seconds

Propagation k sub p= 8.33 dm^3 mol^-1 s^-1

termination, k sub t= 9.3 X 10 ^6 dm ^3 mol ^-1 s^-1

transfer to monomer k sub trm= 3.93 X 10 ^-3 dm^3mol^-1s^-1

Transfer to solvent k sub trS= 7.34 X 10 ^-3 d, ^3 mol ^-1 s^-1

Assume that the initiator efficiency f=0.7 that the termination by combinaition is negligible, and that the density of the initial solution of MMA in toluene is 860 g dm^-3

A 14 kg projectile is launched at 380 m/s at a 55 ∘ angle to the horizontal. At the peak of its trajectory it collides with a second projectile moving horizontally, in the opposite direction, at 140 m/s . The two stick together and land 9.8 km horizontally downrange from the first projectile's launch point.

Find the mass of the second projectile.

Write the code of:
– an abstract class called Creature
– classes Player and Monster (derived from Creature)
– classes WildPig and Dragon (derived from Monster)

In the Creature class
– Define a string member, Creature Name, to store the class Creature’s name.(name should be dynamically allocated)
– Define Two virtual pure functions

• void DoAction() : Print the action of the object, and the actions have to be different from different classes.

• void DrawOnScreen() : Print the object’s name and call DoAction() belonging to the same class.
The class definition of Creature is:


Question: Implement the class Player, Monster, Dragon and Wildpig so that when execution the following code, the counsel shows the execution result as the following:

You are a member of an alpine rescue team and must get a box of supplies, with mass 2.20 kg , up an incline of constant slope angle 30.0 ∘ so that it reaches a stranded skier who is a vertical distance 3.50 m above the bottom of the incline. There is some friction present; the kinetic coefficient of friction is 6.00×10−2. Since you can't walk up the incline, you give the box a push that gives it an initial velocity; then the box slides up the incline, slowing down under the forces of friction and gravity. Take acceleration due to gravity to be 9.81 m/s2.

Part A. Use the work-energy theorem to calculate the minimum speed v that you must give the box at the bottom of the incline so that it will reach the skier.
