GROUP PROBLEM SOLVING 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=(0.4t2)m/s, where t is in seconds. Find: Force in the cable and distance s when t=5 s. 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.
