A football player catches a pass 60 m from the end zone and runs down the sideline at vp = 6.0 m/s.  A defending player directly across on the other sideline, 53.3 yd (48.8 m) away, runs to intercept. If the defending player runs in a straight line, with what minimum speed (in m/s) must they run to intercept the player before reaching the end zone? Quiz 4 prob 4.png

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
