2.5m/s
Explanation:
Given parameters: 
Initial velocity = 0m/s
Acceleration = 0.5m/s²
time of travel = 5s
Solution: 
Final velocity = ? 
Solution: 
 Acceleration can be defined as the change in velocity with time: 
           Acceleration = 
   From the equation above, the unknown is final velocity: 
 Final velocity - initial velocity = Acceleration x time
  since initial velocity = 0
    Final velocity = 0.5 x 5 = 2.5m/s

Answer:
The answer to your question is    vo = 5.43 m/s
Explanation:
Data
distance = d= 5.8 m
height = 3 m
height 2 = 1.7 m
angle = 60°
vo = ?
g = 9.81 m/s²
Formula
               hmax = vo²sinФ/ 2g
Solve for vo²
               vo² = 2ghmax / sinФ
Substitution
               vo² = 2(9.81)(3 - 1.7) / 0.866
Simplification
               vo² = 19.62(1.3) / 0.866
               vo² = 25.51 / 0.866
               vo² = 29.45
Result
               vo = 5.43 m/s
                
 
        
             
        
        
        
No, aluminum has a density near 2.7 g/cm^3
