Q1. Two blocks are connected by a string. The smooth inclined surface makes an angle of 35 degrees with the horizontal, and the block on the incline has a mass of 5.70 kg. The mass of the hanging block is m= 2.90 kg. Find the direction of the hanging block's acceleration. Find the magnitude of hanging block's acceleration.
Q2. Pulling up on a rope, you lift the 4.40 bucket of water from a well with an acceleration of 1.90. What is the tension in the rope?
Two identical speakers are driven by the same oscillator @ 200Hz. They are located on a vertical pole & 4.00 m apart. A man walks straight towards the lower speaker perpendicular to the pole.
Two 53 {rm g} blocks are held 30 {rm cm} above a table. One of them is just touching a 50-long spring. The blocks are released at the same time. The block on the left hits the table at accurately the same instant as the block on the right first comes..

Ricardo and Jane are standing under a tree in the middle of a pasture. An argument ensues, and they walk away in different directions. Ricardo walks 24.0 in a direction 60.0 west of north. Jane walks 12.0 in a direction 20.0 south of west. They then ..
A pendulum of length 1.5 m is held out to point A. At the vertical position, an overhang effectively cuts the length of the pendulum by an amount equal to 1.09 m. (That is, 1.0 m is no longer free to swing.) How long does this pendulum take for one o..
