Ablock of mass m=2.0kg compresses a spring of stiffness k=100n/m by 30 cm. the spring at the bottom of a 15° incline and is oriented in such a way that when the block is released it shoots and moves up the incline. the incline is rough with a coefficient of friction equal to μk=0.2. 1. how far along the incline will the block move before stopping?
2. assuming the block stops momentarily and heads back down to the spring, how fast is the block moving right before it hits the spring?
3. as the block comes to rest, by how much is the spring now compressed? is this supposed to be greater than, less than or equal to the original compression before launch?
