A 32 g bullet is fired horizontally from a rifle at 380 m/s into a water bottle at y pointblank range. The bullet travels completely through the 12 cm long bottle, located 2 m above the ground. (You may assume there is no change in the height of the bullet while travelling through the bottle.) It finally hits the ground at a point 3 m downrange from the point where it left the water. Determine: the average force exerted by...

A gun is fired parallel to the ground. As the bullet leaves the barrel of the gun with a velocity of 200 m/s, find the following (neglecting air resistance): 1. a) Velocity in the x direction (vx) b) Acceleration in the x direction (a) c Velocity in the y direction (Vy) d) Acceleration in the y direction (ay) e) Assuming the barrel is 50m above the ground, calculate how much time passes before the bullet hits the ground. Using your...

A 5.00 g bullet is fired horizontally at a speed of 276 m/s into a 1.50 kg wooden block resting on a frictionless horizontal surface. Determine how fast the block will be moving if the bullet becomes imbedded in the block. Express your answer using appropriate mks units.

A bullet is fired horizontally at a target 20 m away. The velocity of the bullet as it leaves the gun is 200 m/s. How much, approximately, will the bullet drop on its way to the target? Multiple Choice 0.1 m 0.2 m 0.05 m 0.3 m 0.4 m

A bullet is fired at an angle of 28 degrees below the horizontal with a velocity of 165 m/s. The bullet is fired from 6 m above the ground. How long will it take the bullet to hit the ground? How far, horizontally, does the bullet travel? What is the speed of the bullet the instant before it hits the ground?

A 25 gram bullet is fired from a gun with a speed of 200 m/s. If the gun has a mass of 0.9 kg, what is the recoil speed of the gun? 1b 15 gram bullet traveling at 250m/s strikes a block of wood of mass 2.5 kg. With what velocity will the block and bullet move after the collision?

Question 12 A bullet is fired horizontally from a handgun at a target 100.0 m away. If the initial speed of the bullet as it leaves the gun is 300.0 m/s, how far vertically will the bullet have dropped by the time it hits the target? Ignore the effects of air resistance NOTE TO PHYS 1A STUDENTS: This problem originally had an error, so it will not be counted in the HW score whether or not you already entered an...

A projectile is fired horizontally from a gun that is 66.0 m above flat ground, emerging from the gun with a speed of 250 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? m (c) What is the magnitude of the vertical component of its velocity as it strikes the ground? m/s
