1) Using the formula F=ma, we can calculate the force:

F = 0.5 * 0.5 = 0.25 kN

So, the force acting on the object is 0.25 kN.

2) First, convert the speed from km/h to m/s:

V = 36 km/h (1000 m / 1 km) (1 h / 3600 s) = 10 m/s

Then, use the equation V = Vo + at to find the acceleration:

10 = 0 + a * 10
a = 10 / 10
a = 1 m/s^2

Finally, use the formula F=ma to find the force:

F = 0.5 * 0.5 = 0.5 N

So, the force acting on the object is 0.5 N.
