Imagine you are a NASA engineer, and you are asked to design an airbag to protect the Mars Pathfinder from its impact with the Martian plain when it lands. Your system can allow an average force of up to 53,000 N on the spacecraft without damage. Your Pathfinder mock-up has a mass of 540 kg. If the spacecraft will strike the planet at 24 m/s, what is the minimum time for your airbag system to bring Pathfinder to rest so that the average force will not exceed 53,000 N?

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
