Aphysics cart has a projectile launcher mounted on top. while traveling on a straight track at 0.500 m/s, a projectile is fired. it lands back in the same place on top of the launcher after the cart has moved a distance of 2.30 m. in the frame of reference of the cart, (a) at what angle was the projectile fired and (b) what was the initial velocity of the projectile? (c) what is the shape of the projectile as seen by an observer on the cart? a physics student is watching the demonstration from a classroom seat. according to the student, (d) what is the shape of the projectile’s path, and (e) what is its initial velocity?
