A500-g squirrel with a surface area of 1020 square centimeters falls from a 5.5-meter tall tree to the ground. what is its terminal velocity? (use the drag coefficient of a horizontal skydiver, and assume that the density of the air is 1.16 kg/m33).

Terminal velocity will be 9.10 m/sec

Explanation:

We have given mass of squirrel m = 500 gram = 0.5 kg

Area

Density is given as

We have to find the terminal velocity

Terminal velocity is given by , here m is mass, g is acceleration due to gravity , C is drag coefficient,   is density

Here value of drag coefficient C = 1

So terminal velocity

number of electrons for neutral cl

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
