What kind of movement does a projectile in the horizontal direction? (MRU or MRUV) Why?
Homework Answers
For a projectile there is no acceleration acting on horizontal direction ( as the gravity works only in vertical direction) so the horizontal speed of the projectile does not changes hence the motion in the horizontal direction is rectilinear motion with uniform speed that is MRU.
