Answer:
The deceleration is 4 times higher for 0.5sec than for 2 sec.
Explanation:
If the deceleration happens from 1800deg/sec to zero in 2 sec we have that the magnitude is:

if now the time to decelerate is 0.5sec:

The deceleration is now 4 times higher than the previous situation.
C. A complete revolution is 360 degree. two revolution is 720.
Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
