We can use conservation of momentum of the ball-man system. 
mv + mv = mv 
the total momentum of the two objects before the collision is the same as the total momentum of the two objects after the collision 
(95)(0) + (0.14)(18) = (95 + 0.14)Vfinal 
0 + 2.52 = 95.14Vf
divide by 95.14 on both sides 
Final velocity = 0.0265m/s in the direction the ball was initially travelling
        
             
        
        
        
Answer:
0072.00kW
Explanation:
1,200 hours multiply by 60W will give you 72000kW. Convert it to kW. That will give you 0072.00kW.
 
        
             
        
        
        
The final speed of the toy car at the end of the given time period is 3.58 m/s.
The given parameters;
- distance traveled by the car, s = 1.2 m
 - time of motion of the car, t = 0.67 s
 - initial velocity of the car, u = 0
 
The acceleration of the car is calculated as;

The final velocity of the toy car is calculated as;

Thus, the final speed of the toy car at the end of the given time period is 3.58 m/s.
