According to Newtons 2nd law of motion F equals MA so if i was travelling at a constant speed of say 100 km per hour with no acceleration and I smashed into something how can my force equal 0?

Formula for distance traveled?
There is not enough information to answer the question. The answer depends on is the object travelling at constant velocity? is the acceleration constant? If it is an object travelling with constant acceleration, which three of the following four variables are knows: initaial velocity, final velocity, acceleration and time.
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
