Carla holds a ball 1.5 m above the ground. Daniel, leaning out of a car window, also holds a ball 1.5 mabove the ground. Daniel drives past Carla at 40 mph and, just as he passes her, both release their balls at the same instant. Who's ball hits the ground first?

Same instant

Explanation:

Both balls hit the ground at the same instant

When Daniel drops the ball then it has an additional horizontal component of velocity which will cause the ball to move horizontally while falling down,

For both the cases ball has zero initial vertical velocity and needs to cover a distance of 1.5 m .

So time taken to cover 1.5 m vertically will be same
