Answer 1

Question

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

Snoop Dogg, in an effort to get laid back (with his mind on his money and his money on his mind) pours himself a gin and juice. He mixes 0.124 kg (about 3 shots) of gin with 0.576 kg (about a pint) of orange juice. The gin starts at 20.0˚C, room temperature. The juice is refrigerated and starts at 2.89 ˚C. What is the final temperature after mixing of the gin and juice? The specific heat of gin is 3460 J/kg˚C and the specific heat of orange juice is 3730 J/kg˚C.

A sword is heated up to 226 °C, it is put into a nearby barrel of water that is at 18.4 °C. What mass of water would be needed to cool the sword to 30.0˚C, bringing the system to thermal equilibrium? The sword is 35.4 kg and is made of steel. The specific heat of water is = 4186 J/kg ˚C. The specific heat of steel is = 502 J/kg ˚C

You are planning on installing a new above-ground swimming pool in your backyard. The pool will be rectangular with dimensions 32.0 m x 10.0 m. It will be filled with fresh water to a depth of 2.20 m. In order to provide the appropriate structural support, you wish to determine the following. (a) Determine the force exerted on the bottom of the pool by the water (in N). (No Response) N (b) Determine the force exerted on each end of the pool by the water (in N). (Assume the end is the 10.0 m wall.) (No Response) N (c) Determine the force exerted on each side of the pool by the water (in N). (Assume the side is the 32.0 m wall.) (No Response) N (d) You wish to have swimming parties with your children and grandchildren. At a given time, you might have 23 people with an average mass of 75.0 kg in the pool. You need to determine if such parties will affect your calculations for the required strength of materials supporting your pool. The parties will not affect the required strength since…
