The chart lists the masses and velocities of four objects. a 3-column table with 4 rows titled motion data. the first column labeled object has entries w, x, y, z. the second column labeled mass (kilograms) has entries 58, 34, 89, 60. the third column labeled velocity (meters per second) has entries 1, 2, 0.5, 2. which object requires the greatest change in momentum in order to stop its motion? w x y z

Object Z

Explanation:

We add to the table a fourth column to register the linear momentum (P = m*v) for each object so we can easily answer the question (recall that linear momentum is defined as the mass of the object times its velocity):

Therefore, the object with largest momentum is object Z, and it would therefore require the greatest change in momentum to stop it.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
