Question : 85 of 160

Marks: +1, -0

A particle of mass m= 1 kg moves in the x-y plane. The force on it at time t is F(t)=[2sin(αt)

+3cos(αt)

]N, where α= 1 s−1. At time t=0, the particle is at rest at the origin. Calculate the magnitude of its position vector r (in m) and velocity vector v (in m/s) at time t=

r=√[(π−2)2+9];v=√13
r=√13;v=√9
r=√3;v=√2
r=1;v=√5
None of the above
