Homework Statement
A force F = (2ti + 3t^2j) N acts on an object moving in the xy plane. Find the magnitude of change in momentum of the object in time interval t=0 to t=2
(The bold ones are vectors)
Homework Equations
Ft=change in momentum
The Attempt at a Solution
magnitude of F = (4t^2 + 9t^4)^(1/2)
taking t^2 common:
t(4+9t^2)^(1/2)
Ft=delta p
so, delta p = 2t(4 + 9t^2 ) ^ (1/2)
But the answer doesn't have ts in it.
