Sam’s job at the amusement park is to slow down and bring to a stop the boats in the log ride. The boat and its riders have a mass of 910kg . If he applies a constant 445N force and stops the boat... more

A 146 kg motorcycle is driving around a turn with a radius of 87.8 m at a constant speed of 12.1 m/s. What is the minimum force of friction required to prevent the cycle from sliding off of the road?

By how much does the gravitational force between two objects decrease when the distance between their centers is doubled? Tripled? Increased tenfold?
