Aball rolls off the edge of a table with a fairly large horizontal velocity. which of the following statements are true? (select all that apply.) a. the vertical velocity is constantly increasing as the ball falls.
b. the horizontal velocity does not noticeably change as the ball falls.
c. the horizontal velocity decreases significantly as the ball falls through the air.
d. the ball will take more time to fall to the floor than if it had been dropped with no horizontal velocity.
e. the acceleration of the ball changes throughout its flight through the air. f. the ball will take less time to fall to the floor than if it had been dropped with no horizontal velocity.
g. the horizontal velocity does not affect how long it will take the ball to fall to the floor.
h. the velocity vector of the ball changes as it travels through the air.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
