 East of South
Explanation:
Part a)
Velocity of Juan is given as

velocity of the ball is given as

now we have

Part a)
We need to find velocity of ball with respect to Juan
so it is given as



magnitude of the speed is given as


Part b)
direction of velocity of the ball


 East of South

Answer:

Explanation:
The system ball-pin is modelled by the Principle of Moment Conservation:

The velocity of the bowling ball after the collision is:

 
        
                    
             
        
        
        
E = hf
E = 6.63* 10 ⁻³⁴ * 7.24* 10¹⁴
<span>E = 4.80012 × 10⁻¹⁹ J</span>
        
                    
             
        
        
        
The vertical velocity of the projectile upon returning to its original is 17. 74 m/s
<h3>
How to determine the vertical velocity</h3>
Using the formula:
Vertical velocity component , Vy = V * sin(α)
Where
V = initial velocity = 36. 6 m/s
α = angle of projectile = 29°
Substitute into the formula
Vy = 36. 6 * sin ( 29°)
Vy = 36. 6 * 0. 4848
Vy = 17. 74 m/s
Thus, the vertical velocity of the projectile upon returning to its original is 17. 74 m/s
