Mass M1 = 2.25 kg is at the end of a rope that is 2.00 m in length. The initial angle with respect to the vertical is 60.0° and

M1 is initially at rest. Mass M1 is released and strikes M2 = 4.50 kg (also at rest) exactly horizontally. The collision is elastic. After the collision, mass M2 is moving on a frictionless surface but later runs into a rough patch with a coefficient of friction = 0.175 for both kinetic and static friction.
At the end of the rough patch, the object is again on a frictionless surfave and is stopped by a spring with spering constant equal to k=50.0 N/m. Calculating the following
a. Velocities of Masses M1 and M2 after collision
b. The amount the spring is compressed while stopping mass M2
c. What Maximum height after collision does mass M1 obtain?

You can use _______________ to change a liquid into a gas.
Nitella [24]

Answer:

below

Explanation: When a liquid changes into a gas vaporization has occurred. The process can either occur due to boiling or evaporation. Boiling occurs when the vapor pressure of the liquid is raised (by heating) to the point where it is equal to the atmospheric pressure.

You open the refrigerator in your room and put in a case of room-temperature root beer. After an hour, the root beer is ice cold
agasfer [191]

Answer:

warmer

Explanation:

The law of conservation of energy tells us that energy cannot be created or destroyed, it can be transferred or converted from one from to another. In this question when the beer that is at room temperature is put in the fridge, it loses some heat energy. This heat energy is not destroyed, the fridge through  multiple processes eventually releases this heat to the room through pipes at the back which is why they are normally warm. the heat from the food inside is expelled to the room. It is not lost.

The height of the empire state building is 318 m if a stone is dropped from the top of the building what is the stones velocity
lutik1710 [3]

79 m/s. A stone dropped from the top of the Empire State Building will have a velocity of 79 m/s just before it strikes the ground.

This problem is about free fall, to find the velocity of the stone before it strikes the ground we have to use the equation v_{f}^{2}=v_{0}^{2}+2gh, the initial velocity  of the stone is 0 m/s. Then:

v_{f}^{2}=2gh

v_{f}=\sqrt{ 2gh}

Solving the equation above with g = 9.8 m/s², and h = 318.0 m:

v_{f}=\sqrt{ 2(9.8m/s^{2})(318.0m)}= 78.95 m/s

v_{f}≅ 79 m/s
