Projectile Motion 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 70.0 m away, how low will the bullet hit if aimed directly at a target 91.0 m away? The muzzle velocity of the bullet is 270.0 m/s. (Discuss qualitatively how a larger muzzle velocity would affect...

a gun shoots bullets that leave the muzzle at 250 m/s. If the bullet is to hit a target 100m away at the level of the muzzle, the gun must be aimed. How far above the target is this point?

Two runners start at the same point on a straight track. The first runs with constant acceleration so that he covers 109 yards in 9 seconds. The second runner waits 3 seconds and then throws a rock at his opponent's head. If the head and the rock are at the same level form the ground, what must the initial magnitude of the velocity be if the rock is to hit the head just at the 109 yard tape? Give the...

*47. ssm The drawing shows an exaggerated view of a rifle that has been "sighted in" for a 91.4-meter target. If the muzzle speed of the bullet is Vo = 427 m/s, what are the two possible angles t, and θ2 be- tween the rifle barrel and the horizontal such that the bullet wi hit the target? One of these angles is so large that it is never used in target shooting. (Hint: The following trigonometric identity may be useful:...

A toy gun uses a spring with a force constant of 350 N/m to propel a 14.0 g steel ball. The spring is compressed 8.80 cm and friction is negligible. (a) How much force (in N) is needed to compress the spring? (Assume the gun is aimed in the positive direction. Indicate the direction with the sign of your answer.) (b) To what maximum height (in m) can the ball be shot? (c) At what angles above the horizontal (in...

A gun with inertia 5.5 kg fires a 13-g bullet at a stationary target located 1.0 km away. After the bullet leaves the gun, its speed decreases (constant x component of acceleration a = -1.0 m/s2 ) so that the bullet hits the target at 299 m/s. If the direction in which the bullet moves is along a positive x coordinate axis, what is the recoil velocity of the gun?
