Experience as follows :
First, we put Spring on the board and a paper under spring to measure the distances between each point from the beginning to the end point of extension for each weight
Then we increased laod to ( 0.2 n ) the measurement was between the starting...
now I try to sovle this queation by another way anf please help me If it correct or not
Dx = 1/2(v + v0)t
80 = 1/2(8.6 + 17v0)
80 = 4.25 + 17v0
v0 = 75.75/17 =4.45
plese check my answer .
A typical compound archery bow requiers a force of 133 N to hold an arrow at "full drwa " ( pulled back 71 cm ). ssunimg that the bow obeys hooke's law . what is its spring constant ?
did conver 71 to m
did use k = W/x to find spring constant ?
plese help me ?
evaluate the value of extension ( x) which elongate under the action of load (w) of 6 N ? [Use your results obtained from rest 1 ]
please help me How i can solve this question because I don't understand it clearly
A truck covers 80 m in 17 s while smoothly slowing down to a final speed of 5.6 m/s
a ) find its original speed
b) Final its acceleration
I want check my answer :
Dx = 80 m
t = 17 s
v = 5.6 m/s
by appling the rule
Dx = 1/2(v+v0)t
80 = 1/2(5.6 + v0) 17
How find the 3 value of x by using Calculator
u = 4x^3 - 4x = 0
I know this good way to solve iy
4x(x^2-1) = 0
X = 1 or X = -1 or X = 1
but I want a way bu useing a Calculator to find the 3 value of x
plese help me .
