A bag filled with lead shots is dropped from a height of h = 27.4 m. The total mass of the bag is m = 835.0 g. What is the increase in the temperature of the lead shots, after the bag hits the ground? The specific heat of lead is c = 130 J/kgK.
When a manganese bar of mass m is dropped through a height difference Δh, its potential energy changes by the amount mgΔh, where g is the acceleration of gravity, equal to 9.81 m s-2. Suppose that when the bar hits the ground, all that energy is converted to heat, increasing the temperature of the bar. If the specific heat capacity of the material in the bar is 0.479 J K-1 g-1, calculate the height from which the bar must be...
When a palladium bar of mass mis dropped through a height difference Ah, its potential energy changes by the amount mgah, where g is the acceleration of gravity, equal to 9.81 ms. Suppose that when the bar hits the ground, all that energy is converted to heat, increasing the temperature of the bar. If the specific heat capacity of the material in the bar is 0.244 K g calculate the height from which the bar must be dropped to increase...
1 A173.0g lead ball at 155°C is dropped into a calorimeter cup containing 210 g of water at 16.0°c. After equilibrium is reached, the temperature of water is increased to 18.2°C. What is the heat capacity of calorimeter? Assume that calorimeter and water are initially at the same temperature. (Specific heat of water is 4186 J/kg. C and specific heat of lead is 128 J/kg.C) 2. An unknown metal sample of 54 g at 108°C is dropped into a calorimeter...
An object of mass m is dropped from height h above a planet of mass M and radius R. Find an expression for the object's speed as it hits the ground. Express your answer in terms of the variables m, M, h, R and appropriate constants.
3. A lead sphere (c = .031 cal/gm. Deg. C), mass 30 gm., is dropped from a height of 50 m. If it doesn't bounce nor lose heat to the surrounding environment, what will be the temperature increase of the lead? (1 cal. = 4.186j)
golf ball and an equal-mass bean bag are dropped from the same height and hit the ground.The bean bag stays on the ground while the golf ball rebounds. Which experiences the greatest from the ground? A) The golf ball. B) The bean bag C) Both the same. D) The ground. E) Not enough information.
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
An ingot of lead is dropped with an initial velocity of 14 ft/s. When it hits the ground, its temperature has been increased by 0.25 oF. From what height was the ingot dropped (in ft)? Neglect air resistance.
A balloon filled with water is dropped from a height of 20.0 m. At the same time, a dart is fired straight up from the ground below the balloon. The initial speed of the dart is 15.0 m/s. When does the dart hit the balloon and how high above the ground does the dart hit the balloon? Assuming that the balloon breaks instantaneously and that the dart doesn’t affect the motion of the water, how long after the balloon breaks...
