Equations of motion — practice question

Two coins are launched from a level table with the same initial speed $u$. Coin X is launched horizontally. Coin Y is launched at an angle of $30^\circ$ above the horizontal. Both coins strike the horizontal ground and do not rebound. Assume that the air resistance acting on each coin is negligible. Which statement about the motion of the coins is correct?

  • ABoth coins hit the ground with the same speed.
  • BBoth coins travel the same vertical distance.
  • CCoin Y hits the ground before coin X.
  • DCoin Y has a smaller vertical acceleration.
