CALC? You throw a rock downward into water with a speed of ?3mg/k?, where k is the coefficient in Eq. (5.5). Assume that the relationship between fluid resistance and speed is as given in Eq. (5.5), and calculate the speed of the rock as a function of time.

Problem 106P

CALC? You throw a rock downward into water with a speed of 3mg/k?, where k is the coefficient in Eq. (5.5). Assume that the relationship between fluid resistance and speed is as given in Eq. (5.5), and calculate the speed of the rock as a function of time.

Step By Step Solution

Step 1 of 3

The resistance force affecting the rock is given by:

The rock reaches maximum velocity when the force of resistance due to water becomes equal to its weight. That velocity os known as terminal velocity.
