Problem 1: A block of mass is attached by a spring with stiffness =120 N/m to the wall at the top of a slippery ramp as shown in the ±gure. The spring’s relaxed length is =1.0 m. Use , if it is needed. At time t=0 the spring’s length is and the block’s velocity is . The wall is located at and the bottom of the ramp is at .
