Q1. A projectile is fired horizontally from a gun that is 33.0 m above flat ground; emerging from the gun with a speed of 130 m/s. (a) how long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? (c) What is the magnitude of the vertical component of its velocity as it strikes the ground?
Q2. Suppose you wish to fabricate a uniform wire out of 2.6 g of copper. If the wire is to have a resistance of R = 0.25 and if all of the copper is to be used, what must be the length of the wire in m and the diameter of the wire in mm.
