Hi! Please help me on this

Question 1 1 pts Pluto was the smallest planet in our solar system. Its gravitational constant is only 6.0% of Earth's value. If a woman has a mass of 50 kg on Earth, what is her mass (m) and weight (W) on Pluto? (A) m = 50 kg; W = 29 kg (B) m = 29 kg; W = 50 kg (C) m = 50 kg; W = 29 N (D) m = 29 kg; W = 50 N OA OB OC ODQuestion 2 1 pts Four separate forces act on the same object: 200 N north, 60 N west, 80 N south, and 150 N east. Which of the following diagrams best illustrates the vector sum of these forces? a. b. C. d. OA OB OC OD3 A 12 kg object is pushed with a force of 6.0 N east across a floor, the force of friction between the two surfaces is 2.0 N. What is the acceleration of the 12 kg object? 0.67 m/s2, east 0.50 m/s2, east 0.33 m/s2, east 2 0.17 m/s2, east OA O B OC OD D Question 4 1 pts A car has a mass of 1200 kg and accelerates from 0 to 100 km/h in 6.00 s. What is the force applied by the engine? Po 5.56 x 103 N b. 3.33 x 104 N C . 2.00 x 104 N d. 1.20 x 105 N OA O B OC ODQuestion 5 1 pts Bart pulls Lisa on a sleigh with a force of 95 N. Lisa has a mass of 40 kg and the sleigh travels at a constant velocity. What is the coefficient of friction? a. 0.22 b. 0.24 C. 0.26 d 0.28Question 6 1 pts A block with a mass of 2.00 kg sits at rest on a frictionless table, attached to the block over the end of the table is a block with a mass of 1.00 kg. Once the system begins to move what is the acceleration of both blocks? 2.00 kg a. 9.81 m/s2 1.00 kg 4.91 m/s2 3.27 m/s2 2.45 m/s2Question 7 1 pts A rocket with a mass of 2.0 x 105 kg is fired vertically, the engine exerts a constant force of 2.4 x 106 N. What is the resultant acceleration of the rocket? a. 2.2 m/s2 4.4 m/$2 9.8 m/s2 12 m/s2 OA O B OC OD Question 8 1 pts NR 1 A block with a mass of 5.00 kg sits on a frictionless inclined plane. The plane makes an angle of 20.0 to the horizontal. When the block slides down the plane what is the acceleration of the block in m/s2? 5.00 kg {record a three digit response} 20.00Question 9 1 pts NR 2 A 620 N box is sliding down a 45-degree incline. If the acceleration of the box is 0.15 m/s?, then the force is friction is a.b x 10 N. Enter your answer as abc. Question 10 1 pts NR 3 While standing on a horizontal frictionless surface, two students push against each other. One has a mass of 50 kg and the other 40 kg. If the acceleration of the 50 kg student is 0.50 m/s? west, what is the magnitude of the acceleration of the 40 kg student? Question 11 1 pts NR 4 You push your 1000 kg car over a distance of 50.0 m. During this time, the car speeds up from rest to a speed of 5.00 m/s. If your applied force is the only force acting on the car, with how much force did you push
