An apple falls out of a tree and takes 1.75 seconds to strike the ground. what was the velocity of the apple when it hit the ground

Explanation:

The apple is in free fall, therefore we can use the kinematic equations, especifically the which one that relate final speed to acceleration of gravity and time:

The initial speed is zero, since falls out of the tree and recall that . So, Rewriting for final speed:

in physics zero. in muscle fatigue could be high

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat
