Projectile motion I

A projectile is launched at ground level with an initial speed of #\unit{47.10}{m/s}# at an angle of #26.80^\circ# above the horizontal. It strikes a target above the ground #\unit{2.215}{s}# later.

What are the horizontal (#x#) and vertical (#y#) displacements from the launch point to the target?

Let #x_y=0# and #y_0=0#. The positive #x#-direction is from left to right and the positive #y#-direction is upwards. Air resistance is negligible and the magnitude of the acceleration due to gravity is #g = \unit{9.81}{m/s^2}#.

Present your answers with three significant digits.

#x = #

#\unit{\!}{m}#

#y = #

#\unit{\!}{m}#
