College Physics 1
For a fixed initial speed, the range of a projectile is determined by the angle at which it is fired. For all but the maximum, there are two angles that give the same range. Considering factors that might affect the ability of an archer to hit a target, such as wind, explain why the smaller angle (cl

Problem 94GP Playing a Violin The tension in a violin string is 2.7 N. When pushed down against the neck of the violin, the string makes an angle of 4.1 with the horizontal. (a) With what force must you push down on the string to bring it into contact with the neck? (b) If the angle were less than 4.
