A 80-kg astronaut and a 1400-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving it a speed of 0.20 m/s directly away from the shuttle. Seven-and-a-half seconds later the astronaut comes into contact with the shuttle. What was the initial distance from the shuttle to the astronaut
The rms speed of a sample of gas is increased by 3 percent. What is the percent change in the temperature of the gas? What is the percent change in the pressure of the gas, assuming its volume is held constant?
Sketch a graph of maximum kinetic energy, KE max against visible light frequency, v for this experiment Label threshold frequency Vc.
A playground merry-go-round has radius 3-{rm m} and moment of inertia 3000-{rm{ kg}} cdot {rm{m}}^2 about a vertical axle through its center, and it turns with negligible friction.
A motorist driving along a straight road at a constant speed of 60 -m/s. At time t=0 she passes a parked motorcycle police officer and begins to accelerate at the constant acceleration.
find the force exerted by the rope on the bucket. A metallic object is given the negative charge by the process of induction. What happens to object's mass.
illustrate a diagram to show the forces acting on the aircraft while it is flying in a horizontal circle with its wing banked at an angle to horizontal.
A 67 kg person sits on a 3.5kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.8 cm in diam. Determine the pressure exerted on the floor by each leg of the chair; Assume the weight is evenly distributed.

Vector A has a magnitude of 7m and makes an angle of 58o with the positive x axis. Vector B also has a magnitude of 7 m and is directed along negative x axis. Enter your answers in distance then angle (in degrees).
A parachutist descending at the speed of 25 m/s loses a shoe at an altitude of 50 m. (Assume the positive direction is upward.)
A 59kg woman trips while walking down the street. She stumbles forward and falls onto her outstretched right hand. At the instant her hand contacts the ground her whole body is moving downward at a velocity of 9m/s and has a downward acceleration ..
A 0.2 object is swung in a vertical circular path on a string 0.1 m long. The acceleration of gravity is 9.8 m/s^2. If a constant speed of 4.07 m/s is maintained, what is hte tension in string when the object is at the top of the circle? Answer in..
