Answer:
3) 52500N
Explanation:
We use the mathematical definition of impulse as follows;

were F is the force experienced, t is the time of impact, m is the mass of the object and v is the velocity of impact.
Given; m = 4.5kg, v = 35m/s, t = 3 milliseconds
however, 
From equation (1);
.
Substituting all necessary values into equation (2), we obtain the following;
