A 3.00-kg block is sent up a ramp of angle θ equal to 43.0° with an initial velocity ν0 equal to 23.0 m/s. Between the block and the ramp, the coeffiient of kinetic friction is μk equal to 0.50 and the coefficient of static friction is μs equal to 0.80. 1) How far up the ramp (in the direction along the ramp) does the block go before it comes to a stop? (Express your answer to two significant figures.)

Answer #1

Work done by friction and gravity is equal to change in kinetic energy. Final kinetic energy is zero. We use this to find the required distance as shown below***************************************************************************************************

There is a variable amount of friction between a block of mass m and a ramp at an angle θ above the horizontal. The kinetic and static coefficients of friction are equal but vary as µ=Ax, where x is measured along the ramp and x = 0 is the bottom of the ramp. The block is sent up the ramp with an initial speed v0, and comes to a stop somewhere on the ramp. In the following parts, take your...
