Gun sights are adjusted to aim high to compensate for the effect of gravity, effectively making the gun accurate only for a specific range. if a gun is sighted to hit targets that are at the same height as the gun and 100.0m away, how low will the bullet hit if aimed directly at a target 147.0m away? the muzzle velocity of the bullet is 272m/s.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
