A windmill-style softball pitcher executes a pitch in 0.65 s. If her pitching arm is 0.7 m long. what are the magnitudes of the tangential and radial accelerations on the ball just before ball release, when tangential ball speed is 20 m/ s? What is the magnitude of the total acceleration on the ball at this point?

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
