✓ a small piece of putty of mass m₁ is
Inc
fired with velocity v₁; at a stationary wooden block of mass m2 resting on a horizontal table. After a
head-on collision, the putty sticks to the wooden block and the two slide along the surface of the
table together as a single mass.
(A) What equations from conservation are useful for determining V1f and v2f. Simplify equations
and solve for vf in terms of v₁; and the two masses m₁ and m2.
(B) After the collision the two masses slide along the table a distance x before being slowed by
friction and coming to a stop. The coefficient of kinetic friction μk. Solve for the stopping distance
x in terms of the masses m₁ and m2, the initial fired velocity of the putty v₁i, gravity g, and the
coefficient of kinetic friction Uk.
(C) Before the experiment the mass of the putty is determined to be 105 grams, the mass of the
block is 10.5 kg and the putty is fired with an initial speed of 25 m/s. The coefficient of friction
between the block and the table is determined to be 0.15. Determine the expected stopping
distance x.
