What is the stones final velocity
A curling stone, with a mass of 20.0 kg, slides across the ice at 1.50 m/s. It collides head on with a stationary 0.160-kg hockey puck. After the collision, the puck's speed is 2.50 m/s. What is the stone's final velocity?

Water at 20 bar, 400°C enters a turbine operating at steady state and exits at 1.5 bar. Stray heat transfer and kinetic and potential energy effects are negligible. A hard-to-read data sheet indicates that the quality at the turbine exit is 98
How condenser can increase the power developed? And what is back pressure how it will effect the plant efficiency and how the vaccum will increase the power developed by turbine?
Macie pulls a 40 kg rolling trunk by a strap angled at 30° from the horizontal. She pulls with a force of 40 N, and there is a 30 N rolling friction force acting on trunk. What is the trunk's acceleration? Please show work.
In a hydroelectric power plant, water enters the turbine nozzles at 880 kPa absolute with a negligible velocity. Determine the maximum velocity to which water can be accelerated by the nozzles before striking the turbine blades.
Determine the rate of heat loss from the turbine to 3 significant figures in kW. Assume the inlet/outlet kinetic and potential energy changes are negligible.
The structure of a house is such that it loses heat at a rate of 5400 kJ/h per degree Celcius difference between the indoors and outdoors. A heat pump that requires a power input of 6 kW is used to maintain this house at 21 degrees Celsius.
