Question

A group of rescue workers is rescuing a dog from a condemned building. Due to demolition, the building has no stairs leading to the ground level. On the ground, the rescue workers hold the edges of a heavy tarp parallel to the ground, at a height of 1.5 meters (shoulder height). The dog will jump out of the window and onto the tarp. Which action will BEST minimize the force of the impact on the dog?

Answer 1

Answer:

Minimize the elevation or jump distance

Explanation:

The only action that minimizes, the impact force is to reduce as much as possible the height of the jump, the dog, ie the height from the jump point of the building. Since at the time of the jump its speed will increase every second at the rate of 9 [m/ s], that is this low effect of the gravitational acceleration of 9 [m/s^2]

$v_{f}=\sqrt{2*g*h}$

where:

vf = final velocity [m/s]

g = gravity [m/s^2]

h = elevation [m]

As we can see while there is higher height, at a higher speed will impact the ground.
