Question
A projectile is fired from a gun and has an initial vertical velocity equal to 30 m/s.
What is the acceleration of the projectile when it reaches its maximum height?
Its magnitude is 9.8 m/s2 and; its direction is changing.
9.8 m/s?, downward
O m/s2
less than 9.8 m/s-but non-zero.
4.9 mm/s?, downward
