A uniform stick, mass m and length l, is placed in a horizontal plane by hanging it from a massless string attached to the center. A ball of mass M moving with speed V in the plane of the stick. The ball strikes the stick at a distance d from the center. the collision is elastic. Find the resulting translational and rotational speeds of the stick and the resulting speed of the ball. show that the relative speed of the ball and the point of contact on the stick is the same before and immediately after the collision.

A ball of mass 75g is thrown upward with an initial positive velocity, vi, at position A.  

Match the energy transformations taking place for each region of the ball's motion.

What is a codon and how do you identify them in a strand of mRNA? There are 64 potential codons for only 20 amino acids. Why does this occur? Why is it also important to know the start codon before determining what a codon would be in a given strand of mRNA? After answering this first part, explain the difference between the DNA template and coding strands and explain how each strand relates to the mRNA strand that is produced?

Question 3: In your company, there is a manufacturing process that produces a part that inspectors grade as as either 1) Excellent, 2) Fair, or 3) Poor. The probabilities that a part is graded as excellent, fair, and poor are 1/8, 3/8, and 1/2; respectively. A new inspector, Steve, has just started working for your company. After performing three inspections, what is the probability that Steve grades an excellent part before a poor part?

Kento purchased a refrigerator–freezer from the Elway Appliance Shop for $900.  The purchase was made over the phone, after which Elway sent Kento a letter thanking him for the purchase of the refrigerator-freezer. Before the appliance was delivered to him, Kento telephoned Elway and canceled the purchase.  Elway then sued for damages, and Kento raised the defense that the contract was unenforceable.  Elway produced a copy of the letter that it sent Kento.  Does this letter help Elway to win the case?

A loan of $10,000 is amortized by equal annual payments for 30 years at an effective annual interest rate of 5%. The income tax rate level is at 25%. Assume the tax on the interest earned is based on the amortization schedule.

a) Determine the income tax in the 10th year

b) Determine the total income taxes over the life of the loan

c) Calculate the present value of the after-tax payments using the before-tax yield rate. Answer to the nearest dollar.

A car initially traveling at 25.7 m/s undergoes a constant negative acceleration of magnitude 1.80 m/s² after its brakes are applied.

(a.) How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the tires have radii of 0.340 m? (rev)

(b.) What is the angular speed of the wheels when the car has traveled half the total distance? (rad/s)

It requires the seller to make the written warranty terms available to the prospective buyer before the sale.

It does not allow consumers to sue the maker of the warranty for failure to fulfill its terms.

It enforces the seller's obligation to make the terms available only after the sale.

It permits consumers to sue the manufacturer if the manufacturer offers the warranty, but not the retailer even if the retailer grants the warranty.

A 50 m3/s is conveyed down a 5-m wide rectangular channel (n = 0.012) with a slope
of 0.02 m/m. The channel transitions into a second channel with a slope of 0.0008 m/m. A
hydraulic jump occurs on the downstream channel. What is the downstream depth of the
second channel after the jump? What is the depth of the water before the jump? What is
the energy loss due to the jump? How long is the total distance of the hydraulic jump?
