Answer:
I think it's a because it goes thru it and reflects
1. its must be B and 2. must be C
You will use the Pythagorean Theorem to solve it.
c^2 = a^2 + b^2
c^2 = (1.5)^2 + (2)^2
c^2 = 6.25
c = square root of 6.25
c = 2.5
I hope this helps!
Force = change of momentum / time taken
Force = (90x3)/0.6
