013 (part 1 of 2) 10.0 points A 4.6 kg steel ball and 2.5 m cord of negli- gible mass make up a simple pendulum that can pivot without friction about the point O This pendulum is released from rest in a hor izontal position and when the ball is at its lowest point it strikes a 4.6 kg block sitting at rest on a shelf. Assume that the collision is perfectly elastic and take the coefficient of friction between...
An 8.62 kg block of ice at 0 ?C is sliding on a rough horizontal icehouse floor (also at 0 ?C) at 15.7 m/s . Assume that half of any heat generated goes into the floor and the rest goes into the ice. A) How much ice melts after the speed of the ice has been reduced to 10.4 m/s ? B) What is the maximum amount of ice that will melt?
What mass of ice would it take to lower the temperature of 0.5kg of water from 20°C to 0°C. 7. A 100-g piece of iron is heated to 100°C and then dropped into a cavity in a large block of ice at 0°C. How much mass of ice will melt? 8. 50 grams of hot water at 80°C is poured into a cavity in a very large block of ice at 0°C. The final temperature of the water in the...
A block of ice at 0oC whose mass initially is m = 42.1 kg slides along a horizontal surface, starting at a speed v0 = 2.35 m/s and finally coming to rest after traveling a distance d = 2.93 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)
a)A piece of iron block moves across a rough horizontal surface before coming to rest. The mass of the block is 3.3 kg, and its initial speed is 3.2 m/s. How much does the block's temperature increase, if it absorbs 74% of its initial kinetic energy as internal energy? The specific heat of iron is 452 J/(kg · °C). °C b)Some stove tops are smooth ceramic for easy cleaning. If the ceramic is 0.590 cm thick and heat conduction occurs...
