I just need to know how to get the answer

F=150N.
A high wind velocity is defined as quickness of motion or operation; swiftness; or speed.
The speed at which a body's position changes over time in a given direction is known as mechanics. the velocity of activity or reaction; the rate at which something occurs.
Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path. The displacement that an object or particle experiences with respect to time are expressed vectorially as velocity
(1400-1250)
