three vector f1=2i-3j -4k, f2=3i+4j-0k,f3=3i-j+5k act on a body of mass 40g causing it to displace for 10sec from p1 ( 2,3,7 ) to p2 ( 3,6,7 ).

Question

(i) estimate the over all displacement vector.
(ii) estimate the resultant force on the body .
(iii) what is the distance from p1 to p2.
(iv) calculate the work done on the body.
(v)in which plane is the body moving .
