A block of mass M = 15 kg is suspended at rest by two strings attached to walls, as shown in the figure. The left string is horizontal and the right string makes an angle θ = 50° with the horizontal. What is the tension in the left string? (Assume the ring where the strings come together is massless.) Tleft =
A block of mass m1 = 1.95 kg and a block of mass m2 = 5.50 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of θ = 30.0° as shown in the figure. The coefficient of kinetic friction is 0.360 for both blocks. A wedge in the shape of a right trapezoid...

A 28.9 kg mass ( m ) is suspended by the cable assembly as shown in the figure. The cables have no mass of their own. The cable to the left ( T 1 ) of the mass makes an angle of 0.00 ∘ with the horizontal, and the cable to the right ( T 2 ) makes an angle ( θ 2 ) of 34.3 ∘ . If the mass is at rest, what is the tension in each...
A .5 kg ball is suspended from a ceiling by two strings. The ball is at rest String 1 on the left makes a 30 degree angle with the vertical. String 2 on the right makes a 60 degree angle with the vertical What is the magnitude of String 1 compared to String 2 Explain rationale for this answer. Suppose the ceiling is an elevator moving downward with a speed of 2m/s How does tension in string 1 compare to...
1. A mass of 4.00 kg is supported in the X-Y plane by two strings. String 1 pulls up and to the left. String 2 pulls up and to the right. Both strings are attached to the ceiling. String 1 makes an angle of 40.0 degrees with the ceiling. The tension on string 1 is 35.0 N. a) Draw the free body diagram of the mass and two strings. b) What is the magnitude of the X component of the...
1) A 50 kg box is hanging from two strings. String #1 pulls up and left, making an angle of 65o with the horizontal on the left, and string #2 pulls up and to the right, making an angle of 80o with the horizontal on the right. Find the tension in string #2 (on the right side) 2) A box is hanging from two strings. String #1 pulls up and left, making an angle of 70o with the horizontal on...
A mass m = 15 kg is pulled along a horizontal floor with NO friction for a distance d =7.1 m. Then the mass is pulled up an incline that makes an angle θ = 30° with the horizontal and has a coefficient of kinetic friction μk = 0.38. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 30° (thus on the incline it is parallel...
1.A block of mass m = 5.00 kg is pulled along a horizontal frictionless floor by a cord that exerts a force of magnitude F = 12.0 N at an angle θ = 25o . (a) Draw the free body diagram of the block. (b) Find the normal force. 2.Two crates are at rest on frictionless horizontal surface. Both crates are connected by a light rope. A woman wearing golf shoes (so she can get traction on the ice) pulls...
A block with mass m1 = 8.8 kg is on an incline with an angle θ = 32° with respect to the horizontal. The spring is replaced with a massless rope that pulls horizontally to prevent the block from moving. What is the minimum tension in the rope? Now a new block is attached to the string above the first block on the ramp. The new block is made of a different material and has a coefficient of static friction...
