An object moves along a straight line path from P to Q under the action of a force

\left( {4\hat i - 3\hat j + 3\hat k} \right)

N. If the coordinates of P and Q, in metres, are (3,3,-1) and (2,-1,4) respectively, then the work done by the force is

View answer and explanation

Correct option: A

+ 23\,J

Option A (+ 23 J) is correct because the work done is the dot product of the force and the displacement vector.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in

\mathrm{\vec F} = - K\left( {y\hat i + x\hat j} \right)

(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x-axis to the point (a,0) and then parallel to the y-axis to the (a,a). The total work done by the force
