A ball is fired from a canon straight upward with an intial velocity vo.
Assume no air resistance. If the intial velocity vo is doubled, the time to reach the apex of the trajectory.. A): doubles. B): increases by a factor of 4. C): Neither of these. D): Impossible to tell from the information given. If the intial velocity vo is doubled, the maximum height of the ball..

A projectile is fired up at |V0 |=10 m/s
A projectile is fired up at |V0 |=10 m/s. Choose up as (+) direction; ground as y=0. What time does it take to reach ymax, the maximum height? 0 s 1 s 2 s 5 s None of these

A ball is thrown straight up. At the top of its trajectory, its
velocity is zero, acceleration is zero. velocity is non-zero, acceleration is non-zero. velocity is zero, acceleration is non-zero. velocity is non-zero, acceleration is zero. © Eric Mazur, "Peer Instruction" 1997
