A 1250 keg car traveling at a speed of 25.0 m/s rounds a 175 m radios curve. 1. assuming the road is level, determine the coefficent of static friction car's tires and the between the road 2. Assuming the curve is banked and the road is frictionless, determine the bank angie with respect to the horizontal A 40kq child is sitting on a swing, The swing is attached to a tree branch by a single 2.40 m long rope 3. find the tension, in [ NJ in the rope when the child is at rest 4. Once the child is swinging, its speed at the lowest point is am/s. Find the tension, in [N] in the rope at this point. imagine that the swing can go around in a vertical circle, with a velocity of 6 mis at the tops of its motion. find the tension in the rope at this point 6. If the child could swing around in a vertical circle, what minimum velocity in [m/s], would be required at the top of its motion to maintain a uniform circle? A 10- meter-long, is0 kg beam extends horizontally from a wall. one end of the beam is fixed to the wall and the other end is attached to The same wall by a cable that makes an angle of 40 with the horizontal. A 75 kq sign is hung from the beam 2.50 meters from the wall. 7. determine the weight of the sign in EN]. 8. determine the weight of the beam, in CNJ. 9. Determine the magnitude of the tension, In EN] on the cable necessary to keep the system in equilibrium
