Textbook Question
Chapter 5, Problem 5.21DQ
A tennis ball drops from rest at the top of a tall glass cylinder—first with the air pumped out of the cylinder so that there is no air resistance, and again after the air has been readmitted to the cylinder. You examine multiflash photographs of the two drops. Can you tell which photo belongs to which drop? If so, how?

About 80 gram of blood is pumped from the heart during each heartbeat.
The blood starts at rest and has a speed of 0.6 m/sec in the aorta. If the pumping takes 0.17 sec, what is the magnitude of the force on the blood?
You are standing at the top of a cliff that has a stairstep configuration. There is a vertical drop of 6 m at your feet, then a horizontal shelf of 5 m , then another drop of 4 m to the bottom of the canyon, which has a horizontal floor. You kick a 0.44 kg rock, giving it an initial horizontal velocity that barely clears the shelf below
What initial horizontal velocity v will be required to barely clear the edge of the shelf below you? The acceleration of gravity is 9.8 m/s^2 . Consider air friction to be negligible. Answer in units of m/s.
How far from the bottom of the second cliff will the projectile land? Answer in units of m.
Problem 10: While watching the clouds pass by, you notice a European swallow flying
horizontally at a height of h = 21.95 m. When the swallow is directly overhead, it drops an
m = 10.5 kg coconut. Refer to the diagram. From your ornithological studies, you know that the
air-speed of this particular species of swallow, while carrying such a load, is vo = 6.93 m/s.
Neglect air resistance. Assume that your head is at the origin of the coordinate system.
Part (a) Calculate the magnitude, in kilogram squared meters per second, of the angular momentum of the coconut, as observed by you, at the
moment it is released directly overhead.

- You push a small box so that it starts moving with a speed of 1.0 m/s along a rough table. After 1.0 m, the box reaches the edge of the table and lands on the floor 21 cm from the table edge. The surface of the table is 0.8 m above the floor. Determine the coefficient of friction between the box and the table. Determine the speed of the box at the moment it hits the floor.arrow_forwardDandelion seeds have a plume made of thin filaments that create a very large drag coefficient due to subtle aerodynamics as the air moves through and past the plume. The slower terminal speed and longer time in the air provide greater dispersal than would be possible for simple spherical seeds. A 0.63 mg seed has a plume with a cross-section area of 13 mm, and it falls with a terminal speed of 40 cm/s.arrow_forwardTwo frogs of equal masses jump into the air with the same initial speed.

A) At their highest point, frog #2 is moving faster than frog #1.B) At their highest point, both of them have the same amount of gravitational potential energy.

The cannon uses strong elastic bands to propel the performer, much in the same way that a slingshot fires a stone. Setting up for this stunt involves stretching the bands by 3.3 m from their untrained length. He takes 4.8 s to travel between the launch point (where he is free from the bands) and the net into which he is shot.
