A ball is projected in an environment where air resistance can be ignored.

Ignoring air resistance, after being dropped the vertical velocity of a ball immediately before contacting a surface is dependent on: Question 18Answera.the height from which the ball was dropped and gravityb.the height from which the ball was dropped, gravity and the surface texture of the ballc.the height from which the ball was dropped, gravity, the mass of the ball, and surface texture of the balld.the height from which the ball was dropped, the mass of the ball, and surface texture of the balle.the influence of gravity, the mass of the ball and surface texture of the ball

Students investigating the motion of golf balls in a medium perform two experiments where golf balls are introduced into different media.  In the first experiment, the balls are dropped vertically downward into a tank of water.  In the second experiment, the balls are compressed against an ideal spring and then propelled horizontally into a tube filled with air, as shown in the figure below.  As the golf ball moves through a medium, it experiences a drag force FD that opposes its motion, as described by the equation:FD=12CDρAv2𝐹D=12𝐶D𝜌𝐴𝑣2where CD is the drag coefficient, ρ is the medium's density, A is the cross-sectional area of the ball, and v is the velocity of the ball. Question 43The students compress a 40 g golf ball a distance of 80 cm against a spring with spring constant k = 100 N/m.  After it is released from the spring, what is the velocity of the ball as it enters the air-filled tube?A.40 m/sB.45 m/sC.56 m/sD.125 m/sSubmit

A ball is thrown up into the air. At the highest point in its trajectory, the net force acting on it isGroup of answer choicesgreater than its weight.less than its weight, but not zero N.Cannot be determined without additional information.equal to its weight.zero N.

Charlie throws a ball up into the air. While the ball is airborne, which is the greatest force acting on the ball to slow it down?

A ball is projected in a vertical plane as shown in figure with a speed 50 m/s towards a huge wall.The coordinate (in meters) of the point when ball strikes the wall. (Take origin to projection point)
