Question

A child's water pistol shoots water through a I.O-mm-diameter hole. If the pistol is fired horizontally 70 cm above the ground, a squirt hits the ground 1.2 m away. What is the volume flow rate during the squirt? Ignore air resistance.

Answer 1

To calculate the volume flow rate during the squirt, use the formula Q = Av, where A is the area of the hole and v is the velocity of the water. Apply the formulas for area and velocity to find the volume flow rate.

Step-by-step explanation:

The volume flow rate during the squirt can be calculated using the formula: Q = Av, where Q is the volume flow rate, A is the area of the hole, and v is the velocity of the water. The area of the hole can be calculated using the formula: A = πr^2, where r is the radius of the hole. The velocity of the water can be calculated using the formula: v = d/t, where d is the distance the squirt hits the ground and t is the time it takes to hit the ground. By substituting the given values, the volume flow rate can be found.
