A 35.0 kg boy and 28.0 kg girl stand, on frictionless ice, at the center of an ice skating rink.  The girl pushes the boy away.  How far apart are they after boy has slid 4.0 m from the center of the rink?

p6(3).png For the above molecule, M = 16m, d = 1.0 Å (Å = 10-10 m), and the center of mass lies 0.067 Å from the M mass atom.  Determine the angle q for the molecule.

A  5.00 kg object traveling East at 12.0 m/s undergoes a perfectly inelastic collision with a 3.00 kg object traveling West at 10.0 m/s.  Determine the velocity to the center of mass before and after the collision to show it is constant.

How long does it take a dvd to spin up, from rest, to 675 rpm with an angular acceleration of 32.0 rad/s2?

What is the acceleration of a person standing at a latitude of 30.00.  Take the radius of the Earth as 6.38×106 m and its rotational period as 24.0 hrs.

p2(1).png Determine the torque on the door for r = 75 cm, F = 4.0 N, and q = 25.00.

p1(6).png   L = 3.00 m F1 = 12.0 N     F2 = 16.0 N     F3 = 20.0 N θ1 = 70.00       θ2 = 25.00       θ3 = 10.00  Determine the torque about the point B.

The patient has been found to have anti S antibody. From the screen cells below, select the option that will be used, indicating which vial is appropriate for the negative control, and which vial is appropriate for the positive control for phenotyping of red cells. Be specific in identifying the via/s needed for EACH control. No partial credit
