A force $\vec{F} = (2x + 3)\hat{i}$ N acts on a particle as it moves from $x = 0$ to $x = 2$ m. The work done by the force is:

A body constrained to move in Y direction, is subjected to a force given by ${\rm{\vec F}} = \left( { - 2\hat i + 15\hat j + 6\hat k} \right)$ N done by this force in moving the body through a distance of 10m along Y axis?

If the work done by a force is zero, which of the following must be true?

A particle moves from a point $( - 2\hat i + 5\hat j)$ to $(4\hat j + 3\hat k)$ when a force of $(4\hat i + 3\hat j)N$ is applied. How much work has been done by the force?

A force $\vec{F} = (2x + 3)\hat{i}$ N acts on a particle as it moves from $x = 0$ to $x = 2$ m. The work done by the force is:

A block of mass 2 kg is pulled up a rough inclined plane of inclination $30^\circ$ with a constant force $F$ parallel to the incline. The coefficient of kinetic friction between the block and the plane is 0.2. If the block moves with a constant speed of 2 m/s, the power delivered by the force $F$ is:

A force of 1200 N acting on a stone by means of rope slides the stone through a distance of 10 m in a direction inclined at ${60^0}$ to the force. The work done by the force is [Joules].

A body of mass 5 kg is placed at the origin, and can move only on the x-axis. A force of 10 N is acting on it in a direction making an angle of ${60^0}$ with the x-axis and displaces it along the x-axis by 4 metres. The work done by the force is

You lift a heavy book from the floor of the room and keep it in the book–shelf having a height 2 m. In this process you take 5 seconds. The work done by you will depend upon

A person carries a 20 kg suitcase horizontally across a room of length 10 m. How much work is done by the person on the suitcase?

A body moves a distance of 5m along a straight line under the action of a force of 10 N. If the work done is 25 J, then the angel which the force makes with the direction of motion of the body is
