Professional Application During a visit to the International Space Station, an astronaut was positioned motionless in the center of the station, out of reach of any solid object on which he could exert a force. Suggest a method by which he could move himself away from this position, and explain the physics involved.
Can an inanimate object (such as a table) exert a force? Can the magnitude of the force exertedb byan inanimate object change? Explain and give an example.
Is it possible for an object at rest to have only a single force actingon it? If your answer is yes, provide an example. If your answer isno, explain why not.
Why do you feel thrown to the outside when a car in which you are riding goes around a curve, even though there is no force acting on you in that direction? simple explanation
Explain, from a force standpoint, why you need to reduce your normal driving speed aroundcurves when it rains. (Answer in no more than 3 sentences)
Is it possible for an object to be in motion and yet have zero netforce acting on it? Explain
two crates of mass 65 kg and 125 kg are in contact and at rest on a horizontal surface. a 650 N force is exerted on the 65 kg crate. if the coefficient of kinetic friction is 0.08, calculate (a) the acceleration of the system, and (b) the force that each crates exerts on the other.

While jumping on a trampoline, sometimes you land on your back and other times on your feet. In which case can you reach a greater height and why?
As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 61.0 kg. If this fish is moving upward at 3.00 m/s as its head first breaks the surface and has an upward speed of 6.00 m/s after two-thirds of its length has left the surface, assume constant acceleration and determine (a) the salmons acceleration and (b) the magnitude of the force F during this interval.
Professional Application A 75.0-kg person is riding in a car moving at 20.0 m/s when the car runs into a bridge abutment. (a) Calculate the average force on the person if he is stopped by a padded dashboard that compresses an average of 1.00 cm. (b) Calculate the average force on the person if he is stopped by an air bag that compresses an average of 15.0 cm.
