- Jamal and Dayo are lifting a large chest, weighing 207 lb, by using the two rope handles attached to either side. As they lift and hold it up so that it is motionless, each handle makes a different angle with respect to the vertical side of the chest (Fig. P5.76). If the angle between Jamals handle and the vertical side is 25.0 and the angle between Dayos handle and the vertical side of the chest is 30.0, what are the tensions in each handle?

- A mother and her 5-year old daughter are ice skating. While at rest, they face each other then push off eachother with their hands, sending them in opposite directions. Assuming the mother weighs much more than thedaughter, what motion results? The mom accelerates faster because she could push with more force. The little girl accelerates faster because her mom pushed her with more force. They both accelerate at the same rate because their forces are equal and opposite. Although the forces are equal and opposite, mom has more inertia. Hence momtravels slower than the daughterarrow_forwardSuppose there is a box of books with a mass of 10 kg resting on a flat horizontal table, and that the coefficient of static friction between the wooden table and the cardboard box is 0.3. What is the total force on the box as sits on the table at rest? At a minimum, how much force do you have to apply to lift the box off the table vertically? At a minimum, how much force do you have to apply to shift the box horizontally across the table? If someone lifts one side of the table so that its surface is not level, what angle would it be at when the box starts to slide off? Explain your answers.arrow_forwardA horizontal force F pushes against a block of mass m. The mass m in turn pushes against a bigger block of mass M.
