The tolerance -+1 in the 3rd significant digit.

A 0.140 kg ball hits a wall with a velocity of (5.20 m/s ) i + (6.40 m/s ) j+ (4.40 m/s )k. It rebounds from the wall with a velocity of (2.50 m/s ) i + (2.70 m/s ) j-(2.70 m/s )k. In unit-vector notation, what are (a) the change in the ball's momentum, (b) the impulse on the ball, and (c) the impulse on the wall? (a) Number i i k Units + + L. (b) Number i k Units + + (c) Number i k Units + +
