[b]1. A 100g bead is free to slide along a 80cm piece of string ABC. Points A and B of the string are attached to a vertical pole 40 cm apart. When the pole is rotated AB becomes horizontal.
I have attached a diagram of the question.
Find the tension in the string?
Find the speed of the...
My main confusion lies with the fact that there are 3 blocks in contact with each other and not just 2.
Given the fact that Block one has a Fnet of 4N and a force being applied of 24N, a total force in the other direction must be 20N. But that would be from (m2 and m3) how would we get the...
Three blocks are in contact with each other on a frictionless horizontal surface with
m1=1kg
m2=2kg
m3=3kg
A horizontal force of 24N is applied to M1.
a) Find the acceleration of the three blocks
b) Find the net force on each block
c) Find the magnitude of the contact forces...
Ok excellent. That was my starting point as well. My major confusion was it the Vy/Vx that is equivalent to the slope, or is it the Dy/Dx that is equivalent to the slope. After this I am just setting Tan33=Dy/Dx or Vy/Vx and solve for t afterwards.
Can I ask why is it Dy/Dx and not Vy/Vx...
A ski jumper travels down a slope and launches at a horizontal speed of 25m/s. The landing incline slopes off at 33 degrees.
How long is the jumper airborne?
Vx = 25m/s
horizontal motion d=Vt
Vertical Motion, d=v1t + 1/2at2, v1 = 0 as initial vertical speed is 0 off the launch
I am...
