Atrain is moving in uniform velocity and acceleration. a girl inside the train tosses a coin. where would the coin land? a - on her palmb - on the tip of her handc - on the floord - on her wristgive reasons for your answer.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
