If a single constant force acts on an object that moves on a straight line, the object's velocity is a linear function of time. the equation v = v_i + at gives its velocity v as a function of time, where a is its constant acceleration. what if velocity is instead a linear function of position? assume that as a particular object moves through a resistive medium, its speed decreases as described by the equation v = v_i - kx, where k is a constant coefficient and x is the position of the object. find the law describing the total force acting on this object. (enter an expression for the magnitude of the total force. use the following as necessary: m, k, and v.)

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

How to calculate voltage drop in a series circuit

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
