Video transcript

Welcome back everybody. We have a skydiver who has achieved terminal velocity and we are told that terminal velocity is calculated by this equation right here, objects mass or the skydivers mass times the acceleration due to gravity Divided by the drag constant. And we are told that the Skydiver is dropping feet first and our drag constant for that position is 0.15. Let's go ahead and plug in all of these values. We have the square root of mass, which is 62 kg times the acceleration of gravity 9.8, all divided by his drag constant for that position, giving him a terminal velocity of 63. m/s or responding to answer choice B. Thank you guys so much for watching. Hope. This video helped. We will see you all in the next one.

Textbook Question

A pickup truck is carrying a toolbox, but the rear gate of the truck is missing. The toolbox will slide out if it is set moving. The coefficients of kinetic friction and static friction between the box and the level bed of the truck are 0.355 and 0.650, respectively. Starting from rest, what is the shortest time this truck could accelerate uniformly to 30.0 m/s without causing the box to slide? Draw a free-body diagram of the toolbox.

The 'Giant Swing' at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. Each arm supports a seat suspended from a cable 5.00 m long, and the upper end of the cable is fastened to the arm at a point 3.00 m from the central shaft (Fig. E5.50). (a) Find the time of one revolution of the swing if the cable supporting a seat makes an angle of 30.0° with the vertical.
