Question 31 Consider the suspended pendulum. -1 Oos v = 3 m. s m = 200 g А B v= ? 100 mm 80 mm The mass of the pendulum is 200 g. When it swings from a height of 100 mm above its lowest point (position A), the velocity is 3 m-s. What is its velocity when it swings to a height of 80 mm above its lowest point (position B)?​

An observer that stands still as the electron moves by him, will observe

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
