Unformatted text preview: 3. A sphere rebounds as shown from a rigid inclined surface. The initial speed of the ball is 5 m/s and is oriented vertically. If the angle α is 30° and the coefficient of restitution is 0.8, determine the maximum height h reached by the ball after impact with the surface. h v A 4. At an intersection car B was traveling due south and car A was traveling 30° north of east when they crashed into each other. After the collision the two cars stuck together and skidded at an angle of 10° north of east. Each driver claimed they were going the speed limit of 30 mph and tried to slow down but could not avoid the crash because the other driver was going a lot faster. The weights of the two cars are W A =3600lb and W B =2800 lb. Determine which car was going faster and the speed of the faster car if the slower car was traveling at the speed limit. 40º 50º v A =18 ft/sec v B =12 ft/sec +x +y o r 90 @ − B v o r r 10 @ , B A v v ′ ′ o r 30 @ A v North East...
