That would be true because a solid object can cast a shadow
Answer:
120 Ns
Explanation:
The impulse exerted on an object is given by:
where
F is the force applied
t is the time taken
In this problem, we have:
F = 40 N
t = 3.0 s
So, the impulse acting on the boat is
52800000000000000000000000000000000000000000
