A bullet is shot horizontally from shoulder height of h with an initial speed vo; there is a downward acceleration with magnitude g. What is the x-component of its velocity when it hits the ground? O√2gh 2vo Vo -VO A

A particle moves along the x-axis so that its coordinate follows the law x(t) =2t^2 +4, where x is in meters, and t is in seconds. Find the particles velocity (in m/s) O 23 O 7t O. 17.3 4t O none of the above

|A particle covers a distance of 20 µm in 80 ms and then covers 60 µm in 240 ms. What is the average acceleration of this particle?

The motion of a bicycle rider moving in a straight line is shown in the graph below.At what time interval do the acceleration points opposite relative to the velocity vector?

The slotted arm OA rotates about a fixed axis through O. At the instant under consideration, 0 = 26°, Ò = 50 deg/s, and Ö – 14 deg/s². Determine the magnited of the force Fapplied by arm OA and the magnitude of the force N applied by the sides of the slot to the 0.3-kg slider B. Neglect all friction, and let L = 0.74 m. The motion occurs in a vertical plane. B т -L
