A body slipping on a rough horizontal plane moves wioth a deceleationof `4.0 m/s^`. What is cofficient of kineic friction between the block and the plane?

Text Solution

Verified by Experts

Let m=mss of the block
From the freebody diagram,
`R-mg=0`
rarr R=mg…..i`
Again ma=muR=0`
ma=muR`
fro equation i. `ma=u mu g`
`rarr a=mug rarr 4=mug`
`mu=4/g=4/10=0.4`

A block of mass m slips on a rough horizontal table under the action of horiozontal force applied to it. The coefficient of friction between the block and the table is mu . The table does not move on the floor. Find the total frictional force aplied by the floor on the legs of the table. Do you need the friction coefficient between the table and the floor or the mass of the table ?

See Fig. A mass of 4 kg rests on a horizontal plane. The plane is gradually inclined until at an angle theta = 15^@ with the horizontal, the mass just begins to slide. What is the coefficient of static friction between the block and the surface ?

Two blocks of equal mass m are connected by an unstreched spring and placed over a plank moving with an acceleration ′ a ′ as shown in figure. The coefficient of friction between the blocks and platform is μ.

A mass of 4kg rests on a horizontal plane the plane is gradually inclined unitl at an angle =15 with the horizontal the mass just begins to slide what is the coefficient of static friction bwtween the block and the surface

Consider the situatioin shown in figure. The system is released from rest and the block of mass 1.0 kg is found to have a speed 0.3 m/s ater it has descended thrugh a distance of 1 m. find the coefficient of kinetic friction between the block and the table.

A 100 kg block is started with a speed of 2.0 m s^(-1) on a long, rough belt kept fixed in a horizontal position. The coefficient of kinetic friction between the block and the belt is 0.20. (a) calculate the change in the internal energy of the block-belt system as the block comes to a stop on the belt. (b) consider the situation from a frame of reference moving at 2.0 m s^(-1) along the initial velocity of the block. as seen from this frame, the block is gently put on a moving belt and in due time the block starts moving with the belt at 2.0 m s^(-1) , calculate the increase in the kinetic energy of the block as it stops slipping past the belt. (c ) find the work done in this frame by the external force holding the belt.

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it. Also it is found that it takes 5 seconds to slide through the first 10 m if a horizontal force of 15 N is applied and the block is gently pushed to start the motion. Taking g=10 m/s^2 , calculate the coefficient of static and kinetic friction between the block and the surface.

A block of mass m is pushed momentarily along a horizontal surface with an initial velocity u. If mu_k is the coefficient of kinetic friction between the object and surface, find the time at which the block comes to rest.
