A relaxed spring with spring constant k = 60 N/m is stretched a distance di = 59 cm and held there. A block of mass M = 7 kg is attached to the spring. The spring is then released from rest and contracts, dragging the block across a rough horizontal floor until it stops without passing through...

thanks for you guys advice. But I'm still not sure... when we want to find the time, the bullet travels, we have to know the angle first to be able to solve for t. we know the distance in horizontal but since we don't know the angle, what velocity should I use? I mean, x coordiante velocity...

Hi, here is my question. A gun shoots bullets that leave the muzzle at 247 m/s. If a bullet is to hit a target 161.4 m away at the level of the muzzle, the gun must be aimed at a point above the target. (Neglect air resistance.) ________________________________________ How far above the...
