Answer:
2.5 m/s²
Explanation:
Given,
Initial speed ( u ) = 10 m/s
Final speed ( v ) = 20 m/s
Time ( t ) = 4 seconds
To find : Acceleration ( a ) = ?
Formula : -
a = ( v - u ) / t
a = ( 20 - 10 ) / 4
 = 10 / 4
 = 5 / 2
a = 2.5 m/s²
Therefore,
The acceleration of the scooter is 2.5 m/s²
 
        
             
        
        
        
Answer:
 12.7m/s 
Explanation:
Given parameters: 
Mass of diver  = 77kg 
Height of jump  = 8.18m 
Unknown: 
Final velocity  = ? 
Solution: 
To solve this problem, we apply the motion equation below: 
              v²   = u²  + 2gH 
v is the final velocity 
u is the initial velocity 
g is the acceleration due to gravity 
H is the height
  Now insert the parameters and solve; 
        v² = 0²  +  2 x 9.8 x 8.18 
      v  = 12.7m/s
