Challenge Problems
Push your limits with challenges.
Question 1
A car engine exerts a force of 4000 N to position the car over a distance of 50 m. Calculate the work done. If the force is applied at an angle of 30 degrees to the direction of movement, how does that change your calculation?
π‘ Hint: Don't forget to calculate cos(30Β°)!
Question 2
If a person lifts a 10 kg box to a height of 2 meters, calculate the work done against gravity. If the same box is pushed along a surface with no friction for the same height, how does the work done compare?
π‘ Hint: Remember to use mgh for lift work.
