Answer:
The detailed calculations are shown below:
Step-by-step explanation:
(a) impulse delivered to the puck = m (
-
)
= 0.133 (45.2 - 27.7)
= 2.327 kgm/s
(b) impulse delivered to the wall = the net impulse on the wall is nearly 0. Technically speaking, this will actually change the rotation of the earth slightly, accounting for this transfer of momentum.
(c) Impulse = force × time
or, 2.327 = force × 0.03
or, force=

∴ force = 77.567 N
