A large fake cookie sliding on a horizontal surface is attached to one end of a horizontal spring with spring constant k=360 N/m, the other end of the spring is fixed in place. The cookie has a kinetic energy of 20.0 J as it passes through the spring's equilibrium position. As the cookie slides, a frictional force of magnitude 10.0 N acts on it . (a) How far will the cookie slide from the equilibrium position before coming momentarily to rest ? (c) What will be the kinetic energy of the cookie as it slides back through the equilibrium position ?

1.	A large fake cookie sliding on a horizontal surface is attached to one end of a horizontal spring with spring constant k=360 N/m, the other end of the spring is fixed in place. The cookie has a kinetic energy of 20.0 J as it passes through the spring's equilibrium position. As the cookie slides, a frictional force of magnitude 10.0 N acts on it . (a) How far will the cookie slide from the equilibrium position before coming momentarily to rest ? (c) What will be the kinetic energy of the cookie as it slides back through the equilibrium position ?
Answer» ANSWER :(a) 0.307 m ; (B) 13.9 J

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
