Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. on a signal, each skater pushes himself away from the other two across the frictionless ice. after the push, skater a with mass ma = 70.0 kg moves in the negative y-direction at 2.00 m/s and skater b with mass m = 85.0 kg moves in the negative x-direction at 2.50 m/s. find the x- and y-components of the 80.0 kg skater c's velocity (in m/s) after the push. hintvcx= m/svcy=/s

When conducting an investigation to determine which type of fertilizer produces the most flowers on a plant, which variable would be graphed on the x-axis once you collected the data? a. type of fertilizer b. amount of flowers c. amount of water d. number of days that the plants grew

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.

Which of the following best describes the circuit shown below?
