2 Yet another application of vector addition! If there is no current, the boat runs at the speed of 4 m/s perpendicular to the bank. What is its speed relative to the bank if the current is 3 m/s? an object dropped from the rest an object which is thrown upwards at an angle We say that a body is a projectile when it is acted only by the force of gravity PROJECTILE MOTION PROJECTILE MOTION MOTION MOTION an object which is thrown upwards vertically projectile launched horizontally
3 projectile launched at an angle Find the magnitude and direction of the resultant of three displacements 1. Move 300m south 2. Move 400m east 3. Move 500m 60 degrees north of east
