Calculating rolling friction is a fairly straightforward process in most cases. Imagine a car with a mass of m = 1,500 kg, driving on asphalt and with μk,r= 0.02. What is the rolling resistance in this case? Using the formula, alongside Fn= mg (on a ...
19. The Midpoint Method: A Better Way to Calculate Percentage Changes and Elasticities The midpoint formula is preferable when calculating the price elasticity of demand because it gives the same answer regardless of the direction of the change. 中点法:一种计算百分比变化中点法一种计算百分比变化和...
Calculating the Normal Force with the appropriate units For the following Question A 7 kg box is at rest on a table. The coefficients of friction are 0.40 and 0.10 for static and kinetic respectively. Then, a 30 N horizontal force is applied to the box. a. What is the normal force acti...
What is the formula of centripetal force?Centripetal Force:When a car is making a turn on a banked curve, the force required to perform the action is called the centripetal force. The magnitude of centripetal force is directly proportional to the mass of the object....
