A 79.0-kg fullback running east with a speed of 4.00 m/s is tackled by a 93.0-kg opponent running north with a speed of 3.00 m/s. (a) Why does the tackle constitute a perfectly inelastic collision? (b) Calculate the velocity of the players immediately after the tackle. magnitu...
Question Part Points Submissions Used A 45.0-kg girl is standing on a 160-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.44 m/s to the right...
The front 1.20 m of a 1,350-kg car is designed as a "crumple zone" that collapses to absorb the shock of a collision. (a) If a car traveling 22.0 m/s stops uniformly in 1.20 m, how long does the collision last? s (b) What is the magnitude of the average force on the ...
A high-speed photograph of a club hitting a golf ball is shown in the figure below. The club was in contact with a ball, initially at rest, for about 0.0037 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 2.7 102 ft/s, find the average force e...

True or false: It is the case that if an argument is inductively correct then the conclusion is factually correct as well
Sketch a transition phase diagram with two curves; one for C18:0 and a second for C18.1. Label X and Y. Add a third curve for what you might predict would happen if a nonionic detergent like Triton X-100 were present in the C18:0 preparation
