Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.
When a body of mass 0.25 kg is attached to a vertical massless spring, it is extended 5.0 cm from its unstretched length of 4.0 cm. The body and spring are placed on a horizontal frictionless surface and rotated about the held end of the spring at 2.0 rev/s. How far is the spring stretched?
Current Attempt in Progress A 6260-kg satellite is in a circular earth orbit that has a radius of 3.17 × 10' m. A net external force must act on the satellite to make it change to a circular orbit that has a radius of 8.61 x 10° m. VWhat work must the net external force do? Note that the work determined here is not the work Wift done by the satellite's engines to change the orbit. Instead, the work W is W = Wift + Weravitational, where Wgravitational is the work done by the gravitational force.
