Moving water, like that of a river, carries sediment as it moves along its bed. the faster the water flows, the more sediment that is carried and the larger the sediment particles. as the river slows down, the heavier particles of the load will settle out. how can you explain the particle movement based on newton's laws of motion? a) an object remains at rest until a force acts on it. b) for every action there is an equal and opposite reaction. c) the greater the force of the water, the faster the particle accelerates. d) the water and the particle exert a gravitational attractive force on each other.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
