need help..-speed is the distance you travel in a given time. e.g. you travel 60miles in 2 hours your speed is 30miles per hour
motion describes how an object is moving with time. It can be speed ^ o
A 2.40g bullet embeds itself in a 1.40kg block, which is attached to a spring of force constant 750 N/m.
a) If the maximum compression of the spring is 5.60 cm, find the initial speed of the bullet.
I dont understand how to solve for this problem:

What is the mass of the string? In grams-v = √(T/u)
velocity, v
Tenstion, T
mass per length, u
v = (1.60m)/(.057s) = 28.1m/s
Tension = 27.0N
Solve for mass per length
u = .034kg/m
u = m / L
L = 1.60m
This just does not make sense to me.I know that light exhibits wave characteristics as well as a force of about 3 piconewtons per 1 milliwatt of power.So why does light not break the sound barrier whe
A spherical wave with a wavelength of 2.0 m is emitted from the origin. At one instant of time, the phase at r = 4.0 m is pi rad. At that instant, what is the phase atr = 3.5 m and r = 4.5 m?
