Sometimes two skydivers share one parachute. How much larger is going to be their speed when they touch the ground compared to a single skydiver? Assume that both skydivers have the same weight.

Expert Solution

In general the drag force is proportional to the square of the velocity for air.

Drag Force ∝ v²

for a safe landing Drag force should be equal to weight of skydriver

Dragg Force = Weight

Now weight in first case = w (one skydriver)

Weight in second case = 2w (two skydriver)

So the Dragg force will be double for balancing

so Dragg Force ∝( v² )_first

2 x Dragg Force ∝( v² )_second

Hence velocity i n second case of two skydriver will square root of 2 times of velocity in first case of one skydriver

A muon is a type of unstable subatomic particle. When high-speed particles from outer space (sometimes called "cosmic rays") collide with atoms in the upper atmosphere, they can create muons which travel toward the Earth. Suppose a muon created in the atmosphere travels at a speed of 0.971c toward the Earth's surface for a distance of 4.13 km, as measured by a stationary observer on Earth, before decaying into other particles. (a) As measured by the stationary observer on Earth,...
