a block starts at the bottom of a ramp making an angle of θ with the horizontal, at initial speed v0 . as it slides up it slows due to gravity and kinetic friction, eventually coming to a nguyen (tcn522) – hw04 - energy – markert – (56635) 3 stop. static friction is not large enough to hold it at rest and it slides back down the ramp. ~v0 θ when it reaches its initial position, compare its speed to the initial speed v0 . 1. the same as v0 2. less than v0 3. even greater than v0 because of gravity 4. without knowing µs and µk we cannot state precisely how the final speed compares to v0 . 5. not enough information has been provided
