A spring gun is used to launch a metal ball horizontally from a height h1=75.0cm above the floor. Students measure the horizontal range to be R1. The students then lift the spring gun onto a taller table and notice that the ball travels a horizontal distance R2=1.67 R1 when launched from this taller table. What is the height h2 of this taller table?
What is the velocity of each ball after the elastic collision? What will be the highest height of each ball after the elastic collision .
A trombone has an effective length of 160 cm and the speed of sound in air is 345 m/s. Notes are selected by moving a U-shaped tube in or out to change effective length of the trombone.
A puck slides across a smooth, level tabletop at height H at a constant speed vo. It slides off the edge of the table and hits the floor a distance x away as shown in the figure. What is the algebraic relationship between the distances x and H?
If the backpack begins to slide when the spring ( = 150 ) stretches by 2.40 , what is the coefficient of static friction between backpack and table.
A 200 gm block of metal is heated to 100 degrees Celcius in boiling water. This block is after placed in an aluminum calorimeter cup (mass - 30gm; c - .22 cal/g degrees C) containing 180 gm of water at 20 degrees C.
A block starts with a certain speed at the top of a frictionless inclined plane with an unknown angle to the horizontal. To calculate the time required for the block to reach the bottom of the plane.
Physics two skaters with masses of 65 kg and 45 kg, respectively stand 8.0 m apart each holding one end of a rope. If they pull themslevles along the the rope until they meet explain how far does each skater travel?
If the spring stretches by 2.4cm, what is the coefficient of static friction between the backpack and the table.
A thin, flexible metal plate attached at one end to the platform, can be used to measure mass. When the free end of the plate is pulled down and released, it vibrates in simple harmonic motion with a period that depends on the mass attached to the pl..
A 54 {rm kg} ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.5 turns each second. The distance from one hand to other is 1.5 {rm m}. Biometric measurements indicate that each hand typically..
