<span>So we want to know what happens to the momentum of the ball that rolls down hill and hits a box. So we need to use the law of conservation of momentum which states that the momentum must be conserved. It cant be transformed into inertia or mass. It can only be transferred to other object via some interactions like collisions. So it has to be a. transferred to the box and that is the correct answer. </span>
        
             
        
        
        
Answer:
top speed = 17.25 
Total height = 281.19 m
Explanation:
given data 
mass = 75 kg
thrust = 160 N
coefficient of kinetic friction = 0.1
solution
we get here frictional force acting that is 
frictional force =  .............1
   .............1
frictional force = 0.1 × 75 × 9.8 
frictional force = 73.5 N 
and 
Net force acting will be F = 160 - 73.5  N 
F = 86.5 N
so 
Acceleration in the First 15 second  will be 
F = ma .........2
86.5 = 75 × a 
a = 1.15 m/s² 
and 
now After 15 second the velocity will be  as
v = u + at   ..........3
here u is 0 
so v will be 
V = 1.15 × 15
v = 17.25 
and 
now we get travels distance S  in 15 s
s = u × t + 0.5 × a × t²  
here u is 0 
so distance s will be 
s = 0.5 × a × t²   
s = 0.5 ×  1.15 × 15²   
s = 129.37 m
and 
now  acceleration acting is 
F =   
   
m a =   
 
a = 
a = - 0.98 
here it is negative it mean downward nature of acceleration 
and 
now we get distance s by this formula 
V² - u² = 2 a s    
here v velocity is 0  and 
u initial velocity is 17.25 m/s
put here value 
0 - 17.25² = 2 × (-0.98) × s    
solve it we get 
s = 151.82 m 
so 
Total height is 
Total height = 129.37 m + 151.82 m
Total height = 281.19 m

Answer:
The value of the inductance is 1.364 mH.
Explanation:
Given;
amplitude current, I₀ = 200 mA = 0.2 A
amplitude voltage, V₀ = 2.4 V
frequency of the wave, f = 1400 Hz
The inductive reactance is calculated;

The inductive reactance is calculated as;

where;
L is the inductance 

Therefore, the value of the inductance is 1.364 mH.
