## Applied Mechanics and Graphic Statics Two objects moving with uniform speeds are 5 m apart after 1 second when they move towards each other and are 1 m apart when they move in the same direction. The speeds of the objects are:

3 m/sec and 2 m/sec
4 m/sec and 6 m/sec
2 m/sec and 2 m/sec
3 m/sec and 3 m/sec
