Question
Part D
Give the magnitude and direction of the unknown force on the hammer when the hammer was at point A.
In this case, give your direction in terms of an angle in degrees measured counterclockwise (CCW) from the Northerly direction. The angle may be anything between 0 and 180 degrees. If your calculation results in an angle that would have to be measured clockwise (CW) from the Northerly direction, then give a negative angle.
ANSWER: magnitude, direction =___250,90.0__ N, degrees CCW from North
Part E
Give the magnitude and direction of the unknown force on the hammer when the hammer was at point B.
In this case, give your direction in terms of an angle in degrees measured counterclockwise (CCW) from the Northerly direction. The angle may be anything between 0 and 180 degrees. If your calculation results in an angle that would have to be measured clockwise (CW) from the Northerly direction, then give a negative angle.
ANSWER: magnitude, direction =__________ N, degrees CCW from North
Consider the following motion diagram for a 2.40-kg water bottle attached to the inside of a newly-designed car during several laps of time trials on a circular racetrack. The dots of the motion diagram are equally-spaced around the circular path. Note that the Up direction for this motion diagram is out of the plane of the page (and Down is into the page). A careful analysis of the motion diagram data indicates that the magnitude of the water bottle's acceleration during its circular motion was 4.90 m/s2 . (Figure 5) Assume that we know that there are only two forces acting on the water bottle at any time and that one of the forces is always the force of gravity on the bottle by the Earth. The other force (which may be of different size and direction at different times in the motion diagram) is unknown.
Part F
For point A, give the magnitude and direction of the unknown force.
In this case, give your direction in terms of an angle in degrees from the Northerly direction. Since the force will only have Up-Down and North-South components, the angle will NOT be in the plane of the page. The angle may be anything between 0 and 180 degrees. Once you have found the angle, decided whether the angle is measured as Up from North, or Down from North. If Up from North, then enter a positive angle; if Down from North enter a negative angle.
ANSWER: magnitude, direction =__________N, degrees Up from North
