[OpenStax College Physics 2e: Two-dimensional kinematics] Two-dimensional motion: Two-dimensional motion
Projectile motion I: problems-exercises_1
A projectile is launched at ground level with an initial speed of #\unit{29.40}{m/s}# at an angle of #25.80^\circ# above the horizontal. It strikes a target above the ground #\unit{1.570}{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}# |
