A block of mass M is resting on a horizontal, frictionless table and is attached as shown above to a relaxed
spring of spring constant k. A second block of mass 2M and initial speed vo collides with and sticks to the first
block. Develop expressions for the following quantities in terms of M, k, and vo
a. v, the speed of the blocks immediately after impact
b. x, the maximum distance the spring is compressed
1984B2. Two objects of masses Ml = 1 kilogram and M2
a. Calculate the x and y components (p
= 4 kilograms are free to slide on a horizontal frictionless
surface. The objects collide and the magnitudes and directions of the velocities of the two objects before and after
the collision are shown on the diagram above. (sin 37° = 0.6, cos 37° = 0.8, tan 37º = 0.75)
x and py, respectively) of the momenta of the two objects before and after
the collision, and write your results in the proper places in the following table.
b. Show, using the data that you listed in the table, that linear momentum is conserved in this collision.
c. Calculate the kinetic energy of the two-object system before and after the collision.
d. Is kinetic energy conserved in the collision?
