Answer 2

Answer:

We need to get the acceleration function for both axes.

We get this by differentiation of the two functions twice :

dx/dt = 10t (speed)

dv/dt = 10(acceleration)

dy/dt = 9t² (speed)

dv/dt = 18t

at t = 2 the acceleration equals :

18 × 2 = 36m/s²

Force = mass × Acceleration

Force on Y :

3 × 36 = 108 N

Force on X:

3 × 10 = 30N

Resultant force is the sum of the two forces since they are perpendicular.
