- "The fastest throw of a rugby ball was 48.0 mph (77.25 km/h) and was achieved by Joe Simpson (UK), a professional rugby player for London Wasps, in an event organized [...] in 2011" (source: Guinness World Records) At what speed must a 150-kg rugby player be moving to have the same momentum as the 450 g rugby ball recorded in the Guinness World Records?Answer: _____ Units:______In an attempt to imitate Miley, Betty White launches herself onto a wrecking ball. If she is moving at 6 m/s when she jumps on the ball, how high does the ball swing? Assume: mbetty = 60 kg (~140 lbs) 450 kg (~1000 Ibs) Mball And that the initial velocity is purely in the horizontal direction, and the support chain of the wrecking ball has negligible mass. a) Solve for the maximum swing height symbolically b) Solve for the maximum swing height numerically c) If the wrecking ball support chain has a length of 5 meters, what angular displacement does the ball have from vertical at the highest point?Is the following statement true? If not, why? Within the system, both the momentum and kinetic energy are conserved during each of the collisions ( spring-loaded elastic, hoop spring, and putty collisions).
- A 980-kg sports car collides into the rear end of a 2500-kgkg SUV stopped at a red light. The bumpers lock, the brakes are locked, and the two cars skid forward 2.9 mm before stopping. The police officer, estimating the coefficient of kinetic friction between tires and road to be 0.80, calculates the speed of the sports car at impact. Question: What was the speed sports car at impact? v=??Calculate the final speed of a 110-kg rugby player who is initially running at 8.00 m/s but collides head-on with a padded goalpost and experiences a backward force of 1.76×104 N for 5.50×10-2 s .A train engine’s mass is 22500 kg and is moving at 25 m/sec, and hits an empty train car with a mass of 7500 kg. What velocity would the empty train car have after impact? (no friction in this system, of course)
- A 2.5 kg ball is dropped from the top of the building. Drag on the ball is negligible, and it landed on the ground 5.3 seconds after it was released. Find the momentum of the ball as it reaches the ground.Yong had stopped his cart which has a mass of 500 kg just before a 30degree hill covered in ice. He was stuck from behind by a 1500 kg coach with a mass of1500 kg which is travelling at 20 m/s. The two vehicles stuck together and slid up the hill. How far up the slope did they go?An object at rest explodes and breaks into two pieces that move away. Which statement can never be correct? Both pieces have the same speed. Both pieces have the same momentum. Both pieces have the same mass.
