Answer:
A×B=C×D
500×0.5=250×X
250=250×X
X=250/250=1
X=1 m
Explanation:
note: if the force plus two, the distance will be half.

Answer:
Refer to the attachment for solution (1). 
<h3><u>Calculating time taken by it to stop (t) :</u></h3>
By using the second equation of motion, 
→ v = u + at
- v denotes final velocity
- u denotes initial velocity
- t denotes time
- a denotes acceleration
→ 0 = 5 + (-5/6)t
→ 0 = 5 - (5/6)t
→ 0 + (5/6)t = 5
→ (5/6)t = 5
→ t = 5 ÷ (5/6) 
→ t = 5 × (6/5) 
→ t = 6 seconds
→ Time taken to stop = 6 seconds
 
        
             
        
        
        
Answer:
-1m/s
Explanation:
We can calculate the speed of block A after collision 
According to collision theory:
MaVa+MbVb = MaVa+MbVb (after collision)
Substitute the given values 
5(3)+10(0) = 5Va+10(2)
15+0 = 5Va + 20
5Va = 15-20
5Va = -5
Va = -5/5
Va = -1m/s
Hence the velocity of ball A after collision is -1m/s
Note that the velocity of block B is zero before collision since it is stationary 
 
        
             
        
        
        
Let t = Theta and p = Phi
Tan t = y/x    Then x =y/Tant.
Tant = y/(x-d)  x-d = y/Tanp
y/Tant  - d = y/Tanp
y -d*Tanr = y*Tant/Tanp
y-y*Tant/Tanp  =  d*Tanr
y(1 - Tanr/Tanp = d*Tant
y = d*Tant/(1-Tant/Tanp)
