Two astronauts are working on the lunar surface to install a new telescope. The acceleration due to gravity on the moon is only 1.64 m/s2. One astronaut tosses a wrench to the other astronaut, but the speed of throw is excessive and the wrench goes over her colleague's head. Which of the following occurs when the wrench is at the highest point of its trajectory?
Its velocity and acceleration are both nonzero.
Its velocity and acceleration are both zero.
Its velocity is zero but its acceleration is nonzero.
Its velocity is zero but its acceleration is zero.
Insufficient information is given to choose between any of the previous choices.
