A uniform plank that is 4.00 m long has a mass of 7.00 kg. The plank is supported by two sawhorses, one 3.56 m from the right end of the plank and the other 1.50 m from the right end of the plank. A cat of mass 2.63 kg is sitting on the plank at a distance of 1.75 m from the right end of the plank. (a) Draw a free body diagram showing the four forces acting ON the...

2. A 10 kg cat walks along a 3 m long plank with a mass of 4 kg that is supported by two sawhorses. The right sawhorse is 0.7 m from the end of the plank. How far from the end of the right sawhorse can she walk before tipping the plank over. 3. Nintendo has designed a new minigame for the next Sonic Party.

This question is worth 20 marks Figure 2 shows a decorator's plank, which is 5 m in length, supported on two trestles. The mass of the plank is 37 kg and the mass of the decorator is 70 kg. In order to paint a stairwell the decorator has to position themselves at point A, as shown on Figure 2. To stop the plank tipping, the decorator's assistant attaches weights to a rope at point B Figure 2 The decorator's plank...
A horizontal 8 kg plank is 3.0 m in length and has its center of mass at the geometrical center. A 2 kg mass is placed 1.0 m from one end and the plank is supported from the ends. Calculate the forces of support Please explain! I keep getting the negatives and positives mixed up in calculations. Thank you!
A 45.0 kg girl is standing on a 159 kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.38 m/s relative to the plank. (a) What is her velocity relative to the surface of ice? 1 m/s (b) What is the velocity of the plank relative to the surface of ice? 2 m/s
1. A 4-meter plank weighing 8 kg is lying on a dock with 2.71 meters of its length on the dock, and the rest of its length extending off the dock. If a child weighing 61.2 kg walks out onto the part of the plank extending off the dock, what is the maximum distance in meters that the child can walk on the plank from the edge of the dock before he falls into the water? 2.

A 45.0-kg girl is standing on a 156-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.44 m/s to the right relative to the plank. (Let the direction the girl is moving in be positive. Indicate the direction with the sign of your answer.) (a) What is her velocity relative to the surface of ice?...
A 45.0-kg girl is standing on a 130-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface.
