Transcript of LPH 105 W15 4.5

" I'm struggling to understand how to incorporate the velocity into the equation when determining forces."
"Are we just using the equation given from Newton's second law the majority of the time? F=ma? "

30
50 kg
If you are to hold this block in place with no friction, what is the tension?
What is the normal force?
F = 25
m = 2
m= 5
What is the acceleration of the blocks?
What is the force between them?
10 kg
25 kg
What is the acceleration of the triangle, if released?
What is the tension, in the string?
If held in place...
m = 3
m = 1
y = 1.5
What is tension when released?
How fast is the triangle moving when the block hits the ground?
T = 239 N
F =325 N
N
a=3.57 m/s^2
F = 17.9 N
a=2.8 m/s^2
T=70 N
T = 14.7 N
V=3.83 m/s
