... 4.5 cm in a tree. Subsequent measurements showed that the tree would exert a stopping force of 70N on the straw. What was the straw’s speed when it hit the tree? Since the stopping force (70 N) is so much larger than the weight of the straw (0.0049 N), we may assume that the net work done is essenti ...

... The force exerted by a spring is equal to the spring constant times the distance the spring is compressed or stretched from its equilibrium. In this equation, k is the spring constant, which depends on the stiffness and other properties of the spring, and x is the distance that the spring is stretch ...

Introduction to Circular Motion
... The formulas used in UCM (uniform circular motion) are: acp = v2/r and Fcp = mv2/r and as always units are important. The mass, m, must be in kg, the velocity, v, must be in m/s, and the radius, r, must be in meters. We will restrict the motion of the object to that of a horizontal circle, i.e. a ci ...
