Question

Item 16 Part A A rock trom a volcanic eruption is launched straight up into the air with no appreciable air resistance. Which one of the following statements about this rock while it is in the air is correct? On the way down, both is velocity and acceleration are downward, and at the highest point both its velocty and acceleraltion are zero O On the way up, its acceleration is downward and its velocity is upward, and at the highest point both its velocity and acceleration ace zero Throughout the motion, the acceleration is downward, and the velocilty is always in the same drection as the acceleration O The acceleration is downward at all points in the motion except that is zero at the highest poin The acceleration is dowward at all points in the motion Submit Request Answer

Explanation / Answer

Option 5.

The acceleration acting on the rock will be due to gravity, which always acts in a downward direction at all points of the motion.

The velocity will be zero at the maximum height.
