(a) if the mass is not attached to the spring, how far up the slopewill the mass move before coming to a rest?
(b) if the mass is attached to the spring, how far up the slopewill the mass move before coming to a rest?
(c) Now if the incline has a coefficient of kinetic friction. Ifthe block, attached to the spring, is observed to stop just as itreaches the spring's equilibrium postion, what is the coefficientof friction?

A block of mass  is attached to a spring of spring constant (see the figure). The other end of the spring is attached to a support while the mass rests on a rough surface with a coefficient of friction of  that is inclined at angle of .The block is pushed along the surface till the spring compresses by  and is then released from rest.

a) How much potential energy was stored in the block-spring-support system when the block was just released?

b) Determine the speed of the block when it crosses the point when the spring is neither compressed nor stretched. 

c) How far up the incline from the initial compressed position does the mass come to rest?

A ball of mass 3.00 kg is attached to a cord of negligible mass.The cord is 2.00 m long and is attached to a fixed point at theother end. The ball is released from rest when the cord ishorizontal. When it is at its lowest point, the ball undergoes anelastic collision with a block of mass 1.50 kg that rests on ahorizontal surface. The coefficient of kinetic friction between theblock and the surface is .100.
a) What is the speed of the block just after the collision?
b) How far does the block move before coming to rest?


A 0.80-kg plastic block, placed on rough surface with coefficientof kinetic friction is firmly attached to a light horizontal spring(spring constant, k = 160 Nm-1). It is found that the mass-springsystem, when compressed 10.0 cm and released from rest (as shown inFigure 2a), stretches out 6.6 cm beyond the equilibrium position(xo) before stopping and turning back (as denoted in Figure2b).

i) By using Work-Energy theorem, show that the coefficient offriction between the block and the surface is 0.347.

ii) The block’s first stop is at position x = - 6.6 cm as shown inFigure 2b. After that, the block is moving to the right and reachesits second stop. Find the position of its second stop.
