U2 L1 EOE Forces A horse is pulling a wagon, on the back of the wagon is a barrel a.) Draw a free body diagram for |. The horse. II. The wagon Ill. The barrel b.) Label each force Identify each force Use Newton's rst law to explain the following I. Blood rushes from your head to your feet when riding on a descending elevator which suddenly stops. II. To dislodge ketchup from the bottom of a ketchup bottle, the bottle is often turned upside down, thrust downward at a high speed and then abruptly halted. For each force diagram, decide if the forces appear to be balanced or unbalanced. Write the expression for the net force in the x- or ydirection. Use the directions right or up as positive. What type of motion will be the result: acceleration or restfconstant velocity? An elevator and its load have a combined mass of 1600 kg and experience a force of gravity of 15680 N. It is initially moving downwards at 12 mfs. Find the tension in the supporting cable when the elevator is brought to rest with a constant acceleration in a distance of 42 m. [ANS 18 000. N]
