Description: On one occasion during the current mission,James Bond throws a stone from the top of abuilding upward at an angle of 30.0° to thehorizontal with an initial speed of 20.0 m/sas shown in the figure. The height fromwhich the stone is thrown is 45.0 m a

The initial speed of the stone: The launch angle: The initial height of the stone: Time: The x-component of the initial speed of the stone can be calculated as,The x-component of the initial speed of the stone can be calculated as,Since there is no acceleration in the horizontal direction, the x-component of the speed remians unchanged.Therefore, the x-component of the speed after is .The acceleration in the vertical direction is equal to the negative of the acceleration due to gravity, i.e. .The formula for the y-component of the speed after is,The expression for the speed of the stone after is,The correct answer is option A: .
