Unformatted text preview: coefficient of kinetic friction between David and the incline is μ k . Use energy methods to show that the maximum height reached by David is θ μ cot 1 max k h y + = 3. Sarah slides without friction from a height h along a curved water slide. She is launched from a height h /5 into the pool. Determine her maximum airborne height y in terms of h and θ . Answer : ( 29 1 sin 4 5 2 + = h y 4. A glider of mass m 1 = 1.60 kg initially moving to the right with a speed of 4.00 m/s on a frictionless horizontal airtrack collides elastically with a spring attached to a second glider of mass m 2 = 2.10 kg initially moving to the left with a speed of 2.50 m/s. Find the velocities of the two gliders after the collision. Answer: v 1f = 3.38 m/s v 2f = 3.12 m/s...
