Need help with physics assignment! Thanks!1. Calculate the net force acting on your car when driving with a constant velocity of +20 m/s.What is the net force acting on you at this speed?2. Someone pulls on an empty 15 kg sled with a force of 50 N.a) Calculate the acceleration of the empty sled. b) Calculate the acceleration of the sled whenit has an additional 45 kg passenger riding on it (and the same applied force).3. Two workers push in the same direction on a large crate. One pushes with 80 N of force andthe other pushes with a force of 100 N. If the crate accelerates at 2.0 m/s^2, calculate the mass ofthe crate.4. Two teams of four pull on a rope in opposite directions. The four members of team A pull inthe -x direction with forces of 105 N, 120 N, 95 N, and 110 N. The four members of team B pullin the +x direction with forces of 90 N, 125 N, 95 N, and 115 N. Calculate the magnitude anddirection of the net force on the rope.5. A vehicle has a total mass of 2000 kg and an initial speed of 18 m/s. The driver hits the brakesand stops in 4.2 s. Calculate the force acting on the car.
