got it, forgot to include the mass of the bullet

Homework Statement A bullet of mass m is fired into a block of mass M that is at rest. The block, with the bullet embedded, slides distance d across a horizontal surface. The coefficient of kinetic friction is μk. Find an expression for the bullet's speed vbullet. Express your answer in terms...

It's ok to combine equations from different directions? I thought you have to keep x and y separate until you add the vectors.

A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't attach the cables to the...

a boat takes 3.1 hours to travel 15 km down a river, then takes 5.1 hours to travel the same distance upstream. how fast is the river traveling. I found the boat is traveling at 4.84km/hr down the stream and 2.94 km/hr up it. not sure where to go next. Any help would be appreciated.

Thanks for the welcome! got it, I'm still a bit shaky with vectors.

I'm having troubling finding a launch angel from a set of given velocities. v=2\hat{i}, 4\hat{j} at t=0 v=2\hat{i}, 2\hat{j} at t=1 v=2\hat{i} at t=2 v=2\hat{i}, -2\hat{j} at t=3 the g=-2 on this planet
