The same rocket sled drawn in the figure is decelerated at a rate of199m/s².

A rocket sled moving toward the right is shown. Underneath the sled are two vectors labeledNandwrespectively. VectorNpoints upward and vectorwpoints downward. Toward the bottom right of the rocket is a vectorfwhich points to the left.

What force (in N) is necessary to produce this deceleration? Assume that the rockets are off. The mass of the system is2150kg. (Enter a number.) N
