A mouse of mass 30.0 g falls 110 m down a vertical mine shaft and lands at the bottom with a speed of 8.4 m/s. During its fall, how much work (in J) is done on the mouse by air resistance

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
