# 1, A box with mass 15 kq is pulled D with a force of BON at an angle of Mos The coefficient of friction is 0.3. m @ calculate the net force les (@ calculate the acceleration. @ If the initial velocity is 2 mis, what is the final velocity after 8 seconds ? # 2. We have a block with mass m hooked up to a spring with spring constant 150 N/ m. The period I is 2 sec. The block compresses the spring by 0.3 met What is the spring force on the block? 1) After letting go of the block, what is it's acceleration ? We add a second spring in parallel with spring constant 100 NIM. Calculate the force' and acceleration on the block. K ) M X
