A bullet of mass m=0.5 kg embeds itself in a block of mass M=1.2kg, which is attached to a spring of force constant k=245N/m. If the initial speed of the bullet is v0=1.32m/s, find the maximum compression of the spring.

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Arailroad car collides with and sticks to an identical railroad car that is initially at rest. after the collision, the total kinetic energy of the two cars is a) the same as before. b) half as much as before. c) one third as much as before. d) one fourth as much as before. e) twice as much as before.
