What is the total forward force?
Does the wind increase or decrease your kinetic energy?
A kg airplane is coming in for landing with a velocity whose direction is 5 degrees below the horizontal and with a drag force of 40 kN acting directly rearward. Kinetic energy will due to the net force of .
A crane is lifting construction materials from the ground to an elevation of 60 m. Over the first 10 m, the motor linearly increases the force it exerts from 0 kN to 10 kN. It exerts that constant force for the next 40 m then winds down to 0 N again over the last 10 m, as shown in the figure. What is the total work done on the construction materials?
