A jet plane is flying with a constant speed along a straight line, at an angle of 26.5° above the horizontal, as Figure 4.30a indicates. The plane has weight whose magnitude is 86500 N, and its engines provide a forward thrust of 103000 N. In addition, the lift force (dire...
Part a of the drawing shows a bucket of water suspended from the pulley of a well; the tension in the rope is 107.5 N. Part b shows the same bucket of water being pulled up from the well at a constant velocity. What is the tension in the rope in part b?
An elevator is moving upward at 1.20 m/s when it experiences an acceleration 0.25 m/s2 downward, over a distance of 0.71 m. What will its final velocity be?
A small block with mass 0.0400 kg slides in a vertical circle of radius 0.0700 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.85 N....
FInd the length between the points and the magnitude of that vector will give you the distance. sqrt((0-(-1))^2+(5-2)^2+(1-2)^2)
