Answer:
0.074m/s
Explanation:
We need the formula for conservation of momentum in a collision, this equation is given by,

Where,
 = mass of ball
 = mass of ball
 = mass of the person
 = mass of the person
 = Velocity of ball before collision
 = Velocity of ball before collision
 = Velocity of the person before collision
 = Velocity of the person before collision
 = velocity of ball afer collision
 = velocity of ball afer collision
 = velocity of the person after collision
= velocity of the person after collision
We know that after the collision, as the person as the ball have both the same velocity, then,


Re-arrenge to find  ,
,

Our values are,
 = 0.425kg
= 0.425kg
 = 12m/s
= 12m/s
 = 68.5kg
= 68.5kg
 = 0m/s
= 0m/s
Substituting,


<em />
<em>The speed of the person would be 0.074m/s after the collision between him/her and the ball</em>
 
        
             
        
        
        
Juan lives a hundred miles away from Bill then the average speed that he reaches Bill's Home in 50 seconds means that Juan lives 50 seconds away from bill because 50 + 50 seconds equals 100 seconds so Juansorry my bad Juan lives 50 miles away from Belle but he probably how I must have run to get to bill in 50 seconds .

Answer:
The time taken to travel is, t = 12 minutes
Explanation:
Given data,
The speed of the car, v = 60 km/h
The distance of travel, d = 12 km
The time taken for the travel is t = ?
The speed is defined as the distance divided by the time taken to travel. The formula for speed is,
                                   v = d/t
∴                                  t = d/v
                                     t = 12 km / 60 km/h
                                     t = 0.2 h
                                      t = 12 minutes
Hence, the time taken to travel is, t = 12 minutes.
