I'm thinking that you're supposed to divide. So you would divide 5 into 60 and get 12
        
                    
             
        
        
        
Answer:
Work done = -220,000 Joules. 
Explanation:
<u>Given the following data;</u>
Mass = 1100kg
Initial velocity = 20m/s
To find workdone, we would calculate the kinetic energy possessed by the car. 
Kinetic energy can be defined as an energy possessed by an object or body due to its motion. 
Mathematically, kinetic energy is given by the formula;

Where,
- K.E represents kinetic energy measured in Joules. 
- M represents mass measured in kilograms. 
- V represents velocity measured in metres per seconds square. 
Substituting into the equation, we have;
 
 
 
 
K.E = 220,000J
Therefore, the workdone to bring the car to rest would be -220,000 Joules because the braking force is working to oppose the motion of the car.

If only 1 option is correct then it is (D)
All the others can also make one component negative, all depends how u measured the angle.
all the best
