A 2.0-kg object has an acceleration of 1.5 m/s2 at 30o above the – x-axis. Write the force vector producing this acceleration in component form.
Answer to relevant QuestionsIn Exercise 2, if the 35-N force acted downward at an angle of 40° relative to the horizontal, what would be the acceleration in this case? Jane and John, with masses of 50 kg and 60 kg, respectively, stand on a frictionless surface 10 m apart. John pulls on a rope that connects him to Jane, giving Jane an acceleration of 0.92 m/s2 toward him. (a) What is ...If you check your electricity bill, you will note that you are paying the power company for so many kilowatt-hours (kWh). Are you really paying for power? Explain. If a person does 50 J of work in moving a 30-kg box over a 10-m distance on a horizontal surface, what is the minimum force required? A spring has a spring constant of 30 N/m. How much work is required to stretch the spring 2.0 cm from its equilibrium position?
