Differentiate y component of velocity wrt time

Smythe · 2012-05-11 19:42:23

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 = -
