O A soccer player kicks a ball, while imparting spin to bend it. The ball starts on the ground and is kicked with an initial velocity of 15 m/s, at an angle of elevation 30 degrees. Assume the ball was kicked north and the spin creates a constant acceleration a to the west, which is what makes the ball follow a curved path. If the ball lands 8 meters west of the starting point, what is the value of a? Assume the standard value of g = 9.8 m/s².

95 N. 55 N O 55 N. 95 N A baseball is thrown by the centerfielder (from shoulder level) to home plate where it is caught (on the fly at shoulder level) by the catcher. At what point is the magnitude of the ball's velocity at a minimum? (air resistance is negligible) * just after leaving the centerfielder's hand just before arriving at the catcher's mitt at the top of the trajectory velocity is constant during entire trajectory A ball is rolled off a table with an initial speed of 0.24 m/s. A stopwatch measures the ball's trajectory time from table to the floor to be 0.3 s. What is the height of the table? (g = -9.81 m/s2 and air resistance is negligible) IA

An object rolls off a tabletop with a horizontal velocity Vox = 12 m/s. The table is at a height yo = 0.65 m above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, it’s horizontal x-axis lying directly beneath the objects trajectory, and it’s vertical y-axis pointing up. a. How long, in seconds, is the object falling before it hits the floor? b. What’s the horizontal distance, in meters from the edge of the tabletop to where the object lands? c. What is the vertical component of velocity, in meters per second, when the object hits the ground? d. What is the magnitude of velocity when it hits the floor?
