A 0.115-kg remote control 15.8 cm long rests on a table, as shown in the figure below, with a length L overhanging its edge. To operate the power button on this remote requires a force of 0.370 N. How far can the remote control extend beyond the edge of the table and still not tip over when you press the power button? Assume the mass of the remote is distributed uniformly, and that the power button is on the end of the remote overhanging the table.

can you please show me how you got the answer?

Expert Solution

Length of the remote L ' = 15.8 cm

= 0.158 m

Mass of the remote m = 0.115 kg

Force F = 0.370 N

Weight of the remote W = mg

= 1.127 N

Center of mass of the remote x = L ' / 2

= 0.079 m

For moment of forces , F L = W ( x-L)

L = ( W/ F ) (x-L)

= 3.0459 ( x- L)

= 0.2406 - 3.0459 L

4.0459 L = 0.2406

L = 0.05947 m

= 5.947 cm

A 16.3-kg block rests on a horizontal table and is attached to one end of a massless, horizontal spring. By pulling horizontally on the other end of the spring, someone causes the block to accelerate uniformly and reach a speed of 5.99 m/s in 1.37 s. In the process, the spring is stretched by 0.180 m. The block is then pulled at a constant speed of 5.99 m/s, during which time the spring is stretched by only 0.0584 m. Find...

The radius of the roll of paper shown in the figure is 7.6 cm and its moment of inertia is I = 2.9 × 10-3 kg·m2. A force of 2.9 N is exerted on the end of the roll for 1.1 s, but the paper does not tear so it begins to unroll. A constant friction torque of 0.11 m·N is exerted on the roll which gradually brings it to a stop. Assume that the paper's thickness is negligible. (a)...
