Answer:
  F= 600 N
Explanation:
Given that
Initial velocity ,u= 0 m/s
Final velocity ,v= 30 m/s
mass ,m = 0.5 kg
time ,t= 0.025 s
The change in the linear momentum is given as
ΔP= m (v - u)
ΔP= 0.5 ( 30 - 0 ) kg.m/s
ΔP= 15 kg.m/s
We know that from second law of Newtons


Now by putting the values 

F= 600 N
 
        
             
        
        
        
Explanation:
Let x = distance of  from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque
 from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque  about the fulcrum is zero:
 about the fulcrum is zero:
