Q1. A Ferris wheel is a vertical, circular amusement ride with radius 6 m. Riders sit on seats that swivel to remain horizontal. The Ferris wheel rotates at the constant rate, going around once in 6.4 s. Consider a rider whose mass is 70 kg.
Q2. Assume a satellite is in a circular orbit 4.125 Earth radii above the surface of the Earth (5.225 Earth radii from the center of the Earth). By how much does it have to increase its speed in order to be able to escape Earth?
On a very muddy football field, a 100 linebacker tackles a 75 halfback. Immediately before the collision, the linebacker is slipping with a velocity of 8.9 north's and the halfback is sliding with a velocity of 7.9 east's.
Points A and B have electric potentials of 243 V and 129 V, respectively. When an electron released from rest at point A arrives at point C its kinetic energy is KA. When the electron is released from rest at point B, however, its kinetic energy when..

Ricardo and Jane are standing under a tree in the middle of a pasture. An argument ensues, and they walk away in different directions. Ricardo walks 24.0 in a direction 60.0 west of north. Jane walks 12.0 in a direction 20.0 south of west. They then ..
A child's toy consists of a piece of plastic attached to a spring. The spring is compressed against the floor a distance of 2.0 cm and released. If the spring constant is 85 N/m, what is the magnitude of spring force acting on the toy at the moment i..

A particular organ pipe can resonate at 231 Hz, 385 Hz, and 539 Hz, but not at any other frequencies in between. Is it an open or a closed pipe? What is the fundamental frequency of this pipe.
A wheel (radius = 0.20 m) is mounted on a frictionless, horizontal axle. A light rope wrapped around the wheel supports a 0.50-kilogram object, as shown below. When released from rest, the object falls with a downward acceleration of 5.0 m/s2. What i..
A spring stiffness 900 N/m and relaxed length 1m stands vertically on a table. You hold a block of mass 1 kg barely touching the top of the spring. Assume you let the mass down onto the spring certain distance very slowly and view the mass is not mov..
What is the mass of sculpture (in kg) assume that the local acceleration due to gravity is 9.80 m/s2.
