Question

Date: А Force of 3 N and 4 N act on a body simultaneusly at right angle to each other of mass 15kg initially at rest. findworkdone in first second journey. ​

Answer 1

Answer:

F'= 3N

F"= 4N

M=15 kg

As the forces are acting at an angle 90

0

so the net force will be

F= √F'° +F°"+F×cos 90°

F= √9+16 +0

F =√25

F=5N

W=F/M

W=5\15

W=1/3 kgm/s
