The diagram below shows the before and after image of a cannon-cannonball system. Initially, the cannon-cannonball system are combined as a single mass at a resting position. After collision, the cannon and cannonball are separated, each having their own velocities.
the 24.6 kg cannonball leaves the 1696.5 kg cannon at a velocity of 184.2 m/s, what is the magnitude of the recoil velocity of the cannon?

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Aclarinetist, setting out for a performance, grabs his 3.350 kg clarinet case (including the clarinet) from the top of the piano and carries it through the air with an upward force of 24.65 n. find the case's vertical acceleration. indicate an upward acceleration as positive and a downward one as negative.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
