1. One of the Mars Rover vehicles, Sojourner, collected red Martian dust on its wheels as it
rolled along. There is very little water on Mars, so it's not mud; it's actually dust. Explain, in
detail, why the dust clings to the wheels. Be sure to describe forces by name and mention
charging by induction, conducting, or rubbing, if it is appropriate. Also explain what atoms
on Mars must be composed of. (4 points)

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
