1. Consider a pair of forces, one having a magnitude of 50 N and other magnitude of 20 N. The
maximum net force possible for these two forces is and the min
1 An airplane flying directly eastward at a constant speed travels 300 km in 2 h. What is the average
velocity of the plane?
V= Travel Distances/Time = 300km/2h =150km/h
Because the speed is constant and the direction is eastward, so the average velocity
WorkEnergy
Is this Work?
Work
Easiest to start with the notion of work
Work = Force X Distance
Lift a box from the floor, you apply a force to
overcome gravity
Multiply that force by the distance through which you
apply the force and you calculate the am
