Practice Problem: Two-Dimensional Two-Body Problem

The video tutorial explains a physics problem involving a pulley system with two blocks. Block A rests on a frictionless ramp, and Block B hangs vertically. The tutorial explores what happens when the blocks are released, using Newton's laws, tension, and trigonometry. It identifies forces acting on each block, calculates gravitational forces, and determines the net force causing Block A to slide down the ramp, pulling Block B upwards.

What is the mass of block A in the pulley system described?

• 5.0 kilograms

• 3.5 kilograms

• 2.0 kilograms

• 1.3 kilograms

Which force acts on the hanging block in the pulley system?

• Frictional force

• Gravitational force

• Magnetic force

• Electrostatic force

What is the angle of the ramp with respect to the horizontal?

• 50 degrees

• 30 degrees

• 45 degrees

• 60 degrees

How do you calculate the parallel component of the gravitational force on the ramp?

• MG cotangent Theta

• MG tangent Theta

• MG sine Theta

• MG cosine Theta

What is the net force causing block A to move down the ramp?

• 12.7 Newtons

• 26.3 Newtons

• 13.6 Newtons

• 34.3 Newtons
