Question

GROUP PROBLEM-1 SAN FRANCISCO STATE UNIVERSITY Given: The 300-kg bar B, originally at rest, is towed over a series of small rollers. The motor M is drawing in the cable at a rate of v (0.4 t2) m/s, where t is in seconds. Find: Force in the ca ble and distance s whent 5s. Plan: Since both forces and velocity are involved, this problem requires both kinematics and the equation of motion. 1) Draw the free-body and kinetic diagrams of the bar. 2) Apply the equation of motion to determine the acceleration and force. 3) Using a kinematic equation, determine distance
