A satellite has two perpendicular thrusters it can use to maneuver. Suppose the satellite is traveling at 4600 m/s in the x-direction when it fires its thrusters giving an acceleration of 20.0 m/s2 in the x-direction and and acceleration of 15.0 m/s2 in the y-direction. If the thrusters fire for 70 s, in what direction, (in degrees) relative to the x-direction, is the satellite traveling after firing?

A football player catches a pass and runs down the sideline at vp = 6.0 m/s.  A defending player directly across on the other sideline runs to intercept. If the defending player runs at vd = 9.0 m/s in a straight line, at what angle relative to the sideline should they run to intercept the player? Quiz Kinematics in Two Dimensions Problem 2.png

A boat crosses a 150 m wide river flowing at 8.0 m/s to reach a dock directly on the other side.  If the boat motor can propel the boat at 10.0 m/s across the water, how long (in seconds) will it take the boat to reach the dock assuming it travels in a straight line)?
