A body of mass 1 kg begins to move
under the action of a time dependent force
(2ti + 3t2j)N, where i and j are unit
vectors along x and y axis. What power
will be developed by the force at the time
F=ma
m=1
Velocity is obtained by integrating acceleration.
V=t^2+t^3
P=F.v=2t^3+3t^5
@gulamjilani
P=F.v
v is obtained by integrating acceleration
v=t^2i+t^3j
