the displacement of an object of 1 kg mass as a function of time t in xy plane is given by x = 20t + 30t^2 and y = 25  40t in the units of meters
the units of x and y are in meters and t is in seconds
the force acting on the object is
and then there's 5 answers

There is acceleration in the x direction only, and it equals d^x/dt^2 = 60 m/s^2
Multiply that by the mass in kg to get the force in Newtons.
