If you believe that you need additional numerical information to express your understanding, please include them and write down the assumptions. A 10-m 12-kg ladder rested against a smooth wall. A person with 65-kg was on the ladder 1.5 m from the ladder top end. The ground coefficient of fiction is 0.25. Find the minimum safety angle in degrees. The assembly would collapse onto a 35-C heated pool below when safety is ignored. What would be the increase of entropy in the pool water, given a large 20-m by 10-m rectangular pool with water 5-m deep? A 20 kg object on a 37 degree incline is connected to a vertically-hung 2 kg object. The 8 -k g pulley has a radius of 0.4 m. The incline has a coefficient of friction of 0.4. Find the speed of the objects when the 20 kg moves 5m long the ramp. Using the energy method, find the angular speed and angular acceleration of the pulley. A 2-kg mud was thrown upward at 20 m / s for 10-m before colliding with a 5-kg 3-sq meter trap door positioned above. The trap door w as thrown open with the energy gained from the inelastic collision with the up-thrown mud where 55% energy was lost upon impact. Find the maximum angular displacement of the trap door in degrees in the given situation when one side was hinged smoothly onto a wall with I - trap door of 4 kg-meter-meter A nearsighted sheriff fires at a cattle rustler with his trusty six shooter pistol. Fortunately for the rustler, the bullet misses him and penetrates the town water tank, causing leak. If the top of the tank is open to the atmosphere, (a) Where does the stream hit the ground if the hole is 3.00m above the ground? (b) Find the final velocity of the water stream as it hit ground A 3-sq-cm circular cross section cylinder with a 15-kg movable lid w as filled with gas. What would be the number of gas particle when the lid was 0.5 m from the cylinder base when the cylinder was placed upright at the bottom of a 15-m deep pool filled with 20 Celsius water? A 1,5-kg block of ice at 0 degree C is added to an insulated 3-kg cup partially filled with 5.0 kg of water at 12.0 degree C. Find the final temperature (cup specific heat = 2 cal/gram/C, latent heat 80 cal/g)
