Work done by a force F on a body is W = F .s, where s is the displacement of body. Given that under a force F = (2 hat i +3 hat j +4 hat k) N a body is displaced from position vector r_1 = (2 hat i +3 hat j + hat k) m to the position vector r_2 = (hat i +hat j+ hat k) m. Find the work done by this force.

A particle starts with an initial veloctiy (hat(i) + hat(j)) m//s and changes it to (3 hat(i) - 5 hat(j)) m//s in 2 sec. What is the magnitude of displacement of the particle in 2s, if the acceleration is constant ?

A force vec(F)=3hat(i)+ c hat(j)+2hat(k) acting on a particle causes a displacement vec(S)=(2hat(i)-3hat(j)+4hat(k)) in its own direction. If the work done is 8J, then the value of c is

A particle moves from position 3hat(i)+2hat(j)-6hat(k) to 14hat(i)+13hat(j)+9hat(k) due to a uniform force of 4hat(i)+hat(j)+3hat(k)N . If the displacement is in meters, then find the work done by the force.
