G A rope, under a tension of 233 N and fixed at both ends, oscillates in a second-harmonic standing wave pattern. The displacement of the rope is given by . where at one end of the rope, is in meters, and is in seconds. What are (a) the length of the rope, (b) the speed of the waves on the rope, and (c) the mass of the rope

Answer with Explanation:

We are given that

Tension=T=233 N

The displacement of  the rope is given by

a.By comparing with

We get

A=0.32

k=

n=2

m

b.

Speed,

c.Let

Mass of the rope=m

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
