Alight plane is headed due south with a speed of 200 km/h relative to still air. after 1.00 hour, the pilot notices that they have covered only 129 km and their direction is not south but 15.0∘ east of south. (a)what is the wind velocity (magnitude)? (b)what is the wind velocity (direction)?

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?

If the area of a square has increased by a factor of 16, by how much has each side increased?

One soccer player (a) is moving at 4 km/h when she kicks the ball while another soccer player (b) is moving at 8 km/h. what statement accurately compares their kinetic energy if they have the same mass? a) both soccer players have the same kinetic energy. b) player b has twice the kinetic energy of player a. c) player b has four times the kinetic energy of player a. d) their kinetic energy can't be compared without knowing their mass.
