Answer:
You can change the momentum of an object by giving the object more force or less force.
Explanation:
Think about a ball. It is going slow, you push it and you give it more momentum.
 
        
             
        
        
        
Answer:
a) 37.70 m/s
b)710.6 m/s²
Explanation:
Given that ;
Mass of object = 2 kg
Radius of the motion = 2m
Frequency of motion = 3 rev/s
The formula to apply is;
v= 2πrf   where v is linear speed
v = 2×π×2×3 =12π = 37.70 m/s
Centripetal acceleration is given as;
a= 4×π²×r×f²  
a= 4×π²×2×3²
a=710.6 m/s²
 
        
             
        
        
        
Answer:
 29.96m/s
Explanation:
Given parameters: 
Initial speed  = 25.5m/s 
Acceleration  = 1.94m/s²
Time  = 2.3s
Unknown: 
Final speed of the car  = ? 
Solution: 
To solve this problem, we are going to apply the right motion equation: 
     v = u  + at 
v is the final speed
u is the initial speed
a is the acceleration
t is the time taken
  Now insert the parameters and solve; 
       v  = 25.5 + (1.94 x 2.3)  =  29.96m/s
 
        
             
        
        
        
Answer:
the rate of turn at any airspeed is dependent upon the horizontal lift component
