Two velocity each 5 ms/s are inclined to each other at 60degree. Find their resultant

Answer 1

Draw a sketch diagram

2 * 5 cos 30 = 8.66 m/s
at 30 degrees to each

Answer 2

answer with fig

Answer 3

Draw the sketch diagram.
Two velocities= 5m/s
Thita= 60degree
Sin 60degree= √3/2
Cos 60degree= 1/2
R= √25+25+2×5×5×1/2
=√75 =8.66m/s
Bita=tan(5√3/2÷5+5/2)
=tan1/√3
Bita=30degree
