Q1. One of the most powerful cranes in the world operates in Switzerland. It can slowly raise a load of M = 5000 tonnes to a height of h = 16.0 m (1 tonne = 1000 kg). How much work is done by the crane?
Q2. A car moves from a point located 26.0 m from the origin and at an angle of 35.0 from the x-axis to the point located 57.0 m from the origin and at an angle of 60.0 from the x-axis in 2.52 s. What is the magnitude of the average velocity of the car?
