Three different skiers start from rest. They ski from the top of a hill from the same height but take different paths (see the figure). The friction is negligible. Which skier has the largest speed at the bottom of the hill? Three_Skiers_Varying_Track.png

A 10 kg mass is placed on a frictionless horizontal surface. A force of 25 N is applied to the mass in the +x direction. A second force of 40 N is applied to the mass in the –y direction. What force must be applied to the mass, so that its acceleration is 1.20 m/s2 at an angle of 122o? (Angles are measured from the +x direction) 

This is a 120-minute multiple-choice exam.  The exam has 25 questions. Questions must be answered in the order presented, without backtracking. The exam will auto-submit at the end of the 2 hours, so please keep an eye on the timer. Academic Integrity Pledge: Except as outlined in Disability Support Services documents, if appropriate, I attest that the work I will submit in this course is entirely my own work and the time I will spend on this course’s tests, quizzes and assignments is no more than that will be allowed by the professor.

The force on a 5 kg object as a function of position is shown in the figure below. If the object starts from rest what is its velocity after it moves 6m?

Which blood type is the universal receiver?

What surface antigens does Type O have on its red blood cells?

If a woman is Rh- but the fetus is Rh+, she will develop anti-Rh antibodies, causing danger for any successive pregnancies that are Rh+.

Match each glacier type with its correct description.

Where do waves concentrate most of their energy when they interact with the coastline?

The snowfield portion of a glacier that is at the highest elevation and is where mass is added to the glacier is called the zone.
