    A ball is thrown with an angle of 45 degrees to the horizontal by a person standing on the ground.

    The y-component of the velocity of ball in projectile motion is differentiated with respect to time. i.e. dv/dt of the y-component of velocity.

    Does this equal -g? (not g)

    dv/dt = -g

    provided you are using the convention of up = +, down = -
