How much volume does an ambu bag deliver?

AMBU bag must deliver between 700 and 1000 milliliters of air to the victim's lungs, but if oxygen is provided through the tubing and if the victim's chest rises with each inhalation (indicating that adequate amounts of air are reaching the lungs), 400 to 600 ml may still be adequate. Squeezing the bag once every 5 seconds for an adult or once every 3 seconds for an infant or child provides an adequate respiratory rate (12 respirations per minute in an adult and 20 per minute in a child or infant).

A child riding a bicycle at 15 meters per second decelerates at the rate of 3.0 meters per second squared for 4.0 seconds What is the child's speed at the end of 4.0 seconds?

The child's final speed after decelerating for 4.0 seconds can be calculated using the equation: final speed = initial speed - (deceleration * time). Plugging in the values, we get: final speed = 15 m/s - (3.0 m/s^2 * 4.0 s) = 15 m/s - 12 m/s = 3 m/s. Therefore, the child's speed at the end of 4.0 seconds is 3 meters per second.


A child kicks a stone along the sidewalk with a force of 520 newtons. The stone travels 1.5 meters in 0.30 seconds. How powerful is the child's kick?

The power of the child's kick can be calculated using the formula: Power = Work / Time. Work is calculated as Force Γ— Distance, which in this case is 520 newtons Γ— 1.5 meters. Time is 0.30 seconds. Therefore, the power of the child's kick is 260 watts.

A child riding a bicycle at 15 meters per second decelerates at the rate of 3.0 meters per second squared for 4.0 seconds what is the child's speed at the end of the 4.0 seconds?

The child's initial speed is 15 m/s. The deceleration rate is 3.0 m/s^2 for 4 seconds. Using the equation of motion, final speed = initial speed + (acceleration x time), the child's speed at the end of 4 seconds will be 3 m/s.

When A child throws a ball up in the air to a height of 3.5 m and catches it at the same point from which he threw it. The ball is in the air for a total of 1.7 seconds. What is the average velocity?

The average velocity of the ball is 0 m/s because it returns to its original position after 1.7 seconds. Since the displacement is zero, the average velocity is also zero.
