A block of mass m moving with a velocity `v_(0)` on a rough horizontal surface from `x=0` coefficient of friction is given by `mu=mu_(0)=ax`. Find the kinetic energy of the block as function of x before it comes to rest.

A rectangular block of size (bbxxh) moving with velocity v_(0) enters on a rough surface where the coefficient of friction is mu as shown in figure. Identify the correct statement.

Time varying force horizontal F=K_(0)t is applied on a block of mass placed at rest on a rough horizontal surface ( mu is coefficient of friction).At a time t=(3 mu mg)/(K_(0)) the acceleration of the block is given by a =p mu g where p=...........( K_(0) is a positive constant)

A block of mass m rests on a rough horizontal surface (Coefficient of friction is µ ). When a bullet of mass m//2 strikes horizontally, and get embedded in it, the block moves a distance d before coming to rest. The initial velocity of the bullet is ksqrt(2mugd), then the value of k is

A small bead of mass m is given an initial velocity of magnitude v_(0) on a horizontal circular wire. If the coefficient of kinetic friction is mu_(k) , determine the distance travelled before the collar comes to rest.

A block of mass 10kg is placed on a rough horizontal surface having coefficient of friction mu=0.5 . If a horizontal force of 100N is acting on it, then acceleration of the will be.

A bullet of mass m is fired at speed v_0 into a wooden block of mass M. The bullet instantaneously comes to rest in the block. The block with the embedded bullet slides along a horizontal surface with a coefficient of kinetic friction mu . Which one of the following expressions determines how far the block slides before it comes to rest (the magnitude of displacement s is as shown in the figure)?
