How do malignant tumors primarily spread to other parts of the body?

A football player catches a pass at the sideline d = 40.0 m from the end zone and runs downfield at an angle of  θ =250 with respect to the sideline at 8.0 m/s.  How long (in seconds) will it take the player to reach the end zone? Quiz Kinematics in Two Dimensions Problem 1 real.png

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 person walks 35 m in a direction of 120 North of East, turn and walks 20 m in a direction of 700 North of East.  How far is the person from where they started?

A cannon fires a projectile with a speed 35 m/s at an angle of 250 up from the horizontal over level ground.  What maximum height  does it reach?

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)?

An object is thrown with a speed 35 m/s at an angle of 250 up from the horizontal from the top of a 55 m tall cliff.  How far from the base of the cliff does the object land?
