When a constant force acts on an object, what does the object's change in momentum depend upon? check all that apply. check all

that apply. the change in momentum depends upon the change in the velocity of the object. the change in momentum depends upon the mass of the object. the change in momentum depends upon the change in the position of the object. the change in momentum depends upon the time interval during which the force acts. the change in momentum depends upon the magnitude of the force?

A book falls off a shelf that is 10.0 m tall. What is the velocity at which the book hits the ground?
Elena L [17]

Answer:

14 m/s

Explanation:

The motion of the book is a free fall motion, so it is an uniformly accelerated motion with constant acceleration g=9.8 m/s^2 towards the ground. Therefore we can find the final velocity by using the equation:

v^2 = u^2 + 2gd

where

u = 0 is the initial speed

g = 9.8 m/s^2 is the acceleration

d = 10.0 m is the distance covered by the book

Substituting data, we find

v=\sqrt{0^2 + 2(9.8 m/s^2)(10.0 m)}=14 m/s

The solid rod shown has a radius of 0.75 in. if it is subjected to the force the 500lb determine the max normal stress developed
Kipish [7]
The normal stress follows the formula written below:

σ = F/A

There are two types of stress, axial and tangential. Since we are only given with the dimension of the radius (and not the length), the possible stress is axial. So, the area is,

A = πr² = π(0.75 in)² = 1.767 in²

So,
σ = F/A = 500 lb/1.767 in² = <em>282.94 psi</em>

Consider a 7 m stretched string that is clamped at both ends. What is the longest wavelength standing wave that it can support (
user100 [1]

A vibrating stretched string has nodes or fixed points at each end. The string will vibrate in its fundamental frequency with just one anti node in the middle - this gives half a wave.

l=\frac{\lambda }{2}

Rearranging for the wavelength

\lambda=2l

\lambda =2(7)

\lambda = 14m

Therefore the longest wavelength standing wave that it can support is 14m
