A sled loaded with firewood is pulled by a tractor. The tractor exerts a constant force with magnitude 2000 N in the horizontal direction. The total weight of the sled and the firewood is 4000 N, and the coefficient of kinetic friction between the sled and the road is 0.200. If the sled travels a distance of 28.5 m, calculate the final velocity of the sled using work-energy theorem (its initial velocity is zero). Maintain standard units. Normal format and 3 SF.

In the last step, are we supposed to multiply by 0.5? If so the answer is .65.  Is this correct?

Can you explain this problem step by step and give answer in 3 significant figures

In the following calculations, be sure to express the answer in standard scientific notation with the appropriate number of significant figures. 3.78 x < 107 g – 4.701 × 105 g - x 10 g

I need the answer to three significant figures. That's what I'm having trouble figuring out

In the following calculations, be sure to express the answer in standard scientific notation with the appropriate number of significant figures. 6.477 × 10 m² 4.7036 x 102 m x 10

The Speed limit on a highway in Lower Slovakia was given as 120,000 furlongs per fortnight. How many miles per hour is this? One furlong is 1/8 mile and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow. Include the given with the required quantities and draw the diagram.

Pls help ASAP. Pls give the significant figures of each of the answer.

Wally wanted to find the volume of a cube. He measured the length of the cube as 4 in. Later, the actual length of the cube was more accurately measured as 4.1 in. What is the relative error in his volume calculation to the nearest hundredth? a. 0.06 b. 0.07 c. 0.08 d. 0.10

Part II. Significant Figures The significant figures in a number are all figures that are obtained from the measuring process and exclude those zeros that are included solely for the purpose of locating the decimal point. This definition will be clarified with a number of examples.
