Question 1) Yves has a mass of 40.0 kg.9 Vo02 From rest, he slides down a slide which is 10.00 m long. The height of the slide is 5.00 m and it forms an angle of 30° with the horizontal. Frictional forces are negligible. The diagram 40.0 kg 10.00 m 5.00 m below illustrates the situation. 30 a) Determine the kinetic energy of the child at the base of the slide. b) What is his velocity when he reaches the water? m.
