<span>You should deflect the
ball in order to maximize your speed on the skateboard.
Since this creates a larger impulse, you want to deflect the ball. Splitting it
up into catching and throwing the ball may by something you can think of deflecting
the ball. First, you need to catch the ball, which in turn would push you
forward with some speed. (The speed we are talking about should obviously be
equal to option A, where you catch the ball). Now, throw the ball back to him
since these two processes are equal to deflecting the ball. Throwing a mass away
from you would cause or enable you to move even fast.</span>
 
        
             
        
        
        
Answer:

Explanation:
Using the tension in the spring and the force of the tension can by describe by 
T = kx
, T = mg
Therefore:

With two springs, let, T1 be the tension in each spring,  x1 be the extension of each spring.  The spring constant of each spring is 2k so:


Solve to x1





 
        
             
        
        
        
Power = (work or energy) / (time)
100 W  =  (energy) / (20 sec)
Energy = 2,000 watt-sec
<em>Energy = 2,000 J</em>
 
        
             
        
        
        
Answer:
Explanation:
Initial velocity , u = 30 m/s
final velocity , v = 10 m/s
time , t = 5 seconds
1. Acceleration = v - u / t 
= 10 - 30 / 5
= -20 / 5
= <u><em>- 4 m/s</em></u>
