7. Sarah pulls her sister in a wagon (combined mass of 50 kg) a horizontal distance of 25 m. If she pulls with a force of 40 N at an angle of 36 degrees with the horizontal distance, how much work does she do. If she starts from rest, what is her power generated

Calculate the linear momentum of a pickup truck that has a mass of 1000kg, and is traveling eastward at 20 m/s
