A space probe is sent to the vicinity of the star Capella, which is 42.2 light-years from the earth. (A light-year is the distance light travels in a year.) The probe travels with a speed of 0.9930c.

ngrid kicks a football with an initial velocity of 12 m/s at an angle of 45° relative to the ground. The horizontal component of the initial velocity to the nearest tenth is m/s.
