1. The scaffold S is raised by moving the roller at A toward the pin at B. Roller A is approaching B with a constant speed of 1.5 ft/s. The 4-ft links AE and BD are pin connected at their midpoint. Find an equation D 4 ft for the speed at which the platform raises as a function of 0. Graph this equation from 10° to 60°. Graphs need to be in the HW submission to have them scored. Be 1.5 ft/s professional, with the plot being a curve (not points) and axes labeled. Ask for help if you need.

A 0.400-kg pendulum bob passes through the lowest part of its path at a speed of 3.00 m/s. (a) What is the tension in the pendulum cable at this point if the pendulum is 80.0 cm long? (b) When the pendulum reaches its highest point, what angle does the cable make with the vertical? (c) What is the tension in the pendulum cable when the pendulum reaches its highest point?
A small particle of mass m is pulled to the top of a friction less half-cylinder (of radius R) by a light cord that passes over the top of the cylinder as illustrated in Figure P7.15. (a) Assuming the particle moves at a constant speed, show that F = mg cos . Note: If the particle moves at constant speed, the component of its acceleration tangent to the cylinder must be zero at all times. (b) By directly integrating W=Fdr, find the work done in moving the particle at constant speed from the bottom to the top of the hall-cylinder. Figure P7.15

In the initial figure, the speeds are known, and the spring is stretched 20.0 cm. In the final figure, the speeds are unknown, and the spring is compressed an unknown amount. Find vi, v2, and the final compression in the spring. You may assume that the system moves on a frictionless, horizontal plane, that system momentum is conserved, and that energy is conserved. initial final 1.00 kg deeleee spring 2.00 m/s 3.00 m/s 30.00 Vị = ? 40.0° 1.00 kg v2 = ? kll
