A2-kilogram [kg] projectile traveling at 120 meters per second [m/s] is stopped by being shot into an insulated tank containing 120 kilograms [kg] of water. if the kinetic energy of the projectile is completely converted into thermal energy with no energy lost, how much will the water increase in temperature in units of degrees celsius [degrees upper c]? the specific heat of water is 1 calorie per gram degree celsius [cal/(g degrees upper c)].

ΔT=0,028  degrees Celsius

Explanation:

There is an energy transformation, then we need to know how to find both kinds of energy, kinetic and thermal.

Kinetic energy:

Thermal Energy

As the energy is always the same in a closed system, we have to equalize:

As we have all the information, we want to find the temperature change, then:

\\\\\\\\\\ΔT=0,028  degrees Celsius" alt="\frac{28800 J}{1203840 J/C }" />

\\\\\\\\\\ΔT=0,028  degrees Celsius" />

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
