A force of 300 lb slows down a wagon from 60 ft/s to 20 ft/s in 10 seconds. What is the weight of the wagon? Choose the correct answer. O W = 3150 lb O W = 1115 lb O W = 2415 lb W = 950 lb A 20kg box is placed in an inclined plane which makes an angle of 30 degrees with the horizontal. Find the force applied parallel to the inclined plane that will make the box move up the inclined plane at a rate of 2 meters per second squared. Choose the correct answer. OF = 158 N OF = 98N OF = 198 N OF = 138 N OF = 48 NAir resistance is a * 1 point CHOOSE THE CORRECT ANSWER O backward force frictional force O gravitational force O balanced force A jolen is thrown vertically upward at a speed of 30 m/s. It is then caught * 3 points on its way down at distance 2m where it is thrown. (a) what is the velocity of the jolen when it was caught? (b) what is the total time of flight of the jolen? Choose the correct answer. Final Velocity = 9 m/s; time = 10 seconds Final Velocity = 39 m/s; time = 15 seconds Final Velocity = 40 m/s; time = 5 seconds Final Velocity = 19 m/s; time = 5 seconds O Final Velocity = 5 m/s; time = 19 seconds
