Question

The figure shows a box of mass m2 = 1.5 kg on a frictionless plane inclined at angle θ = 25°. It is connected by a cord of negligible mass to a box of mass m1 = 3.5 kg on a horizontal frictionless surface. The pulley is frictionless and massless. (a) If the magnitude of the horizontal force is 3.7 N, what is the tension in the connecting cord? (b) What is the largest value the magnitude of may have without the connecting cord becoming slack?

Answer 1

Here's the figure.

Answer 2

are you sure the F's direction is right?

Answer 3

Right out of the text book.

Answer 4

ok let's try it

Answer 5

So we know a number of things. Mass of the blocks, force on the first block, and angle

Answer 6

For block 1, \[N _{1}=m _{1}\] in the y direction. \[m _{1}a _{x}=T+F\] in the x direction.
