Question

Name Directions: Write out your legible answers in the space provided 1. If a weight is hung from a string which has a tension of 100 N, what is the mass of the weight? 2. A rocket moving with a constant accleration that has a mass of 45 kg and an initial velocity of Om/s traveled 300 m in 10s. What is the force of the rocket? hat has a mass of 5.68 x 1026 kg and a diameter of 1.17 x 105 km? 3. What is the gravity of a planet t G 6.673 x 101 N m/kg]

4. There are three objects of masses o kg, 4kg, and 2 kg respectively, If the second object is 20 m enst of the first object and the third object is 10m south of the first object, what is the graviation exerted on the first object? a string that has a 8kg object attached to its other end hanging off the surface by a pully. Meanwhile on its left is attached another string that has a 12 kg object attached to its other end hanging off the surface by a pully. What is the acceleration of the system and the tensions of the strings? 5. Extra Credit: An object of mass 5kg sits on a frictionless horizontal surface. On its right is attarhed
