A particle undergoes three displacements. The first has a magnitude of 15 m and makes an angle of 40◦ with the positive x axis. The second has a magnitude of 6.2 m and makes an angle of 158◦ with the positive x axis.
A particle undergoes three displacements.
The first has a magnitude of 15 m and makes an angle of 40◦ with the positive x axis. The second has a magnitude of 6.2 m and makes an angle of 158◦ with the positive x axis. After the third displacement the particle returns to its initial position.
