A 530-g squirrel with a surface area of 935 cm2 falls from a 4.4-m tree to the ground. Estimate its terminal velocity. (Use the drag coefficient for a horizontal skydiver. Assume that the squirrel can be approximated as a rectangular prism with cross-sectional area of width 11.6 cm and length 23.2 cm. Note, the squirrel may not reach terminal velocity by the time it hits the ground. Give the squirrel's terminal velocity, not it's velocity as it hits the ground.)

Answer with Explanation:

We are given that

Mass of squirrel,m=530 g=

1kg=1000 g

Area=A=

Height,h=4.4 m

C=1

Width of rectangular prism,b=11.6 cm=

1 m=100 cm

Length,l=23.2 cm=

Area=

Terminal velocity,

Where

Using the formula

The velocity of person,

Using the formula

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

not too sure thinking all accelerations are pointed down
