An object traveling 50 m/s comes to a stop in 4 seconds. what is its acceleration

Acceleration = (change in speed) / (time for the change)

Change in speed = (speed at the end) - (speed at the beginning).

Change in speed = (zero) - (50 m/s) = -50 m/s

Time for the change = 4 sec

Acceleration = (-50 m/s) / (4 sec)

Acceleration = -12.5 m/s²

it takes about 30 days for it to break down

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 ! ~
