This is on the same order of magnitude as the result. The amount of power required to overcome the force of air resistance is given by. Since we want to find the change in kinetic energy, we can find the work done as the object moves and then use the work-energy theorem to find the total work done.

Since the object starts at rest at 1. Express the friction force in terms of the speed and weight of the sleigh, and the coefficient of friction between the sleigh and the ground. It is then possible to find the power from the force and velocity. Eventually, it will be necessary to convert from SI units Watts to non-standard units horsepower or hp.

Since the force of the reindeer is equal in magnitude with the friction force, use the equation for frictional force to find: ROUND: The measured quantities in this problem are all given to four significant figures. Though the conversion from watts to horsepower and the gravitational acceleration have three significant figures, they do not count for the final answer.

The power required to keep the sleigh moving is 3. This gives an average of between 0. Work backwards to find that, if the reindeer are pulling the sled with 3. We do not know if the force has a positive or negative y-component. We assumed a positive value, but if it turns out to be negative, then our assumption was incorrect, and the y-component is negative.

The answers should be rounded so they also have two significant figures. Therefore, the minimum force is Just to make sure that our solution is consistent, we can calculate the product of the box's weight and the coefficient of friction and make sure that this product is really smaller than our result for the horizontal component of the force, This is indeed smaller than our result for x F , which shows that some downward force component was indeed needed.

THINK:The torque exerted by a torsional spring is proportional to the angle over which it is displaced. The initial angular displacement gives the spring constant. The additional torque added by the hanging mass will create further angular displacement. Rounding this value is dangerous, since the tank would overflow or possibly explode if L is added. If I assume that the Earth's mass is due to the proton and neutron masses primarily became an electrons mass is much smaller than a protons and I assume that there are an equal number of protons and neutrons than I can get the number of protons by dividing the Earth's mass by two times the mass of a proton.

The mass of a proton is Without glasses the book must be held 12 cm from your eye in order to read clearly. Jack has a near point of near 32 cm 0. Rounding to two significant figures, The measured values in this problem are the constant A in the equation for the force and the two distances on the x-axis. All three of these are given to four significant figures, so the final answer should have four significant figures: 5. The coefficient of kinetic friction between the sleigh and the snow is 0.

The initial diameter of the rod at After the gas is heated up, its final volume is f L. T Since the cross-sectional area remains closely the same,. The initial volume of gasoline is 14 gallons and the change in temperature is 27 F. Table ofofTherefore, a car that consumes To solve the problem it is easiest to draw a velocity versus time graph. The distance is then given by the area under the curve. At the bottom of the swinging motion, there is only kinetic energy, 2.

Let's call the horizontal force component x F and the vertical component y F. The plane mirror cannot change these attributes, so the calculated results agree with these The distance from the lens to the retina at the back of the eye is 2. The focal length can be found with the thin lens equation: The focal length of the lens when viewing a distant object The focal length of the lens when viewing an object P A negative power infers that the focal length is negative, so diverging lenses are being used.

In a nearsighted eye, light comes to a focus before it reaches the retina and diverging lenses are required to correct this. Therefore, you are nearsighted. For nearsighted eyes,27 P 1.
