Scientists aboard the international space station are threatened by a 2.8 kg meteor hurtling toward them at 5.4 x 103 m/s. they deploy an enormous rubber band to catch the meteor.
the rubber band stretches 193 m as it stops the meteor and saves the day. how much average force is applied to the meteor?
a) 3.8 x 104 n
b) 5.2 x 104 n
c) 1.3 x 105 n
d) 2.1 x 105 n
e) 4.7 x 106 n

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
