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. What magnitude of displacement  has the satellite made after firing the thrusters for 70 s?

A boat attempts to cross a 170 m wide river to reach a dock directly on the other side.  The boat heads out directly across the river, perpendicular to the bank, with the motor propelling it at 15.0 m/s across the water, but the river flowing at 5.0 m/s immediately begins pushing it down river.  How far down river ( in meters) from the dock does the boat end up when it reaches the opposite shore?

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 5.00 gram bullet fired from a rifle of barrel length 0.650 m leaves the barrel with a speed of 325 m/s.  Assuming constant acceleration down the barrel, what was the force  acting on the bullet?
