Physics
A bullet is fired horizontally from the roof of a building 100 meters tall with a speed of 850 m/s. Neglecting air resistance, how far will the bullet drop in 3 seconds? 1 29.4 m 2 44.1 m 3 100 m 4 2550 m Answer should be choice 2) 44.1m BUT I DON'T GET IT! Please help me;( if...

A block starts at rest and slides down a fric- tionless track. It leaves the track horizontally, flies through the air, and subsequently strikes the ground. What horizontal distance does the block travel in the air? Answer in units of m. What is the speed of the block when it ...

A block with mass m = 14 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4545 N/m after being compressed a distance x1 = 0.515 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.8...

Physics - Springs
a 10.0 g bullet is fired into a 1.0 kg block initially at rest on a rough surface and connected to a spring with k = 200 N/m. Immediately following the collision the block has a speed of 2.0 m/s. The coefficient of friction between the ground and the block is 0.10. a) If the ...
