A block of mass ๐=2.05 kg slides along a horizontal table withspeed ๐ฃ0=2.50 m/s. At ๐ฅ=0, it hits a spring with spring constant๐=79.00 N/m, and it also begins to experience a frictionforce. The coefficient of friction is givenby ๐=0.300. How far has the spring compressed by the timethe block first momentarily comes to rest?
A 1.0 kg block initially traveling at 6.0 m/s slides up anincline, reaching a vertical height of 0.40 m in 3.0 seconds. The block is still moving at 2.0 m/s when it reaches this higherpoint. The average power exerted by kinetic friction on theblock during this segment of motion is ____ W.
