A ball falls off a cliff. What is the force of gravity on the ball? Assume
Sally is to walk across a “high wire” that has been strung horizontally between two buildings that are apart. The sag (dip) in the rope when she stands at the midpoint is . If her mass is , what is the tension in the rope at this point?
