A physics book slides off a horizontal table top with a speed of 1.30 m/s . It strikes the floor after a time of 0.380s . Ignore air resistance.
Find the height of the table top above the floor.
Find the horizontal distance from the edge of the table to the point where the book strikes the floor
Find the horizontal component of the book's velocity just before the book reaches the floor
Find the vertical component of the book's velocity just before the book reaches the floor.
Find the magnitude of the book's velocity just before the book reaches the floor
Find the direction of the book's velocity just before the book reaches the floor.
Express your answer as an angle measured below the horizontal

a gun is adjusted so that the barrel of the jun is in line with and pointed at the center of a target. the distance from the gun to target is 121.0m. when the gun is fired the bullet hits 10.00cm below the center of the target. find the muzzle velocity of gun?
