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.

Propose a force standard different from the example of a stretched spring discussed in the text. Your standard must be capable of producing the sane force repeatedly.

A sailboat has a mass of 1.50103kg and is acted on by a force of 2.00103N toward the east, while the wind acts behind the sails with a force of 3.00103N in a direction 45 north of east. Find the magnitude and direction of the resulting acceleration.

Find the magnitude of the tension in each supporting cable shown below. In each case, the weight of the suspended body is 100.0 N and the masses of the cables are negligible.

As shown below, if M=6.0kg, what is the tension in the connecting string? The pulley and all surfaces are frictionless.

Shown below is a 30.0-kg block resting on a frictionless ramp inclined at 60 to the horizontal. The block is held by a spring that is stretched 5.0 cm. What is the force constant of the spring?

Check Your Understanding A 50-kg person stands 1.5 m away from one end of a uniform 6.0-m-long scaffold of mass 70.0 kg. Find the tensions in the two vertical ropes supporting the scaffold.

If there is only one external force (or toe) acting on object. It cannot be on equilibrium.
