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...

QUESTION 7 A box is at rest on a horizontal, frictionless table. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 6.75 m/s. Force F3 is also horizontal; it has magnitude 2.85F, and acts at an angle 22.6° to the direction of F1. If forces F1 and F3 act on the box at the same time, find the magnitude...

Extra credit (10 points each) 1. A horizontal merry-go-round has a weight of 600-N and radius of 2.00 m. It is started from rest by a constant horizontal force of 50.0 N applied tangentially to the merry-go- round. Treat the merry-go-round as a solid disk. a) What is the moment of inertia of the merry go round, in kg m?? b) What is the angular acceleration (in rad/sec)? c) What is its angular speed after 4.00 seconds (in...
