A body
of mass 1 kg begins to move under the action of a time dependent force F⃗ =(2i^+3t2j^)N,
where i^i^ and j^j^ are unit vectors along x and y axis.
What power will be developed by the force at the time t ?
Neet
2016 | W P E Q 2 | Power developed by time
varying force will be instantaneous only , which is the dot product of force
and velocity From force , first we calculate acceleration then after
integration of acceleration we can calculate velocity by applying proper
limits. Initial velocity is given zero because body begins to move.
