A physics instructor has setup a projectile gun a horizontal distance d away from the target that is a height h above the ground. The instructor fires the projectile with an initial speed v0 at an angle θ0 with respect to the horizontal. At the instant the projectile leaves the gun, it is initially at the same height above the ground as the target. Ignore air resistance and take the gravitational acceleration g to be known.
a. Write down an vector expression for the initial velocity of the projectile. Clearly indicate your choice of coordinate system along with your choice of unit vectors.
b. Write down a vector expression for the position and velocity of the projectile when it has returned to the same height that is was fired out. Express your answers in terms of v0, θ0, and g.

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
