Explanation:
I have done this before and it was a question on my physics test 
 
        
                    
             
        
        
        
Answer:
v = 7934.2 m/s
Explanation:
Here the total energy of the Asteroid and the Earth system will remains conserved
So we will have

now we know that





now from above formula

now we have

now plug in all data


 
        
             
        
        
        
Answer: angular displacement in rad = 3038.45 rad 
angular displacement in rev = 483.589 rev
Explanation: mathematically 
Angular velocity = angular displacement / time taken. 
Angular velocity = 33.5 rad/s, time taken = 90.7s
33.5 = angular displacement /90.7
Angular displacement = 33.5 * 90.7 = 3038.45 rad
But 1 rev =2π
Hence 3038.45 rad to rev is 
3038.45/2π = 483.599 rev
