1)A 2.0 kg mass, m2, on a 38.5° incline is connected to a 6.8 kgmass, m1, on a horizontal surface. The surfaces and the pulley arefrictionless. If F = 34.5 N, what is the magnitude of the tensionin the connecting cord?
2)A chain consisting of five links, each of mass 0.110 kg, islifted vertically with a constant acceleration of a = 4.4 m/s2.Find the magnitude of the force that link 3 exerts on link 2.
What is the magnitude of the force F that must be exerted on thetop link to achieve this acceleration?
3)The range of a projectile depends not only on v0 and ?0 but alsoon the value g of the free-fall acceleration, which varies fromplace to place. In 1936, Jesse Owens established a world's runningbroad jump record of 8.09 m at the Olympic Games at Berlin (g =9.8128 m/s2)) Assuming the same values of v0 and ?0, by how muchwould his record have differed ( in cm) if he had competed insteadin 1956 at Melbourne (g = 9.7999 m/s2)?
