Answer:
0.15kg/m³
Explanation:
Density = mass/ volume 
Given that 
Mass = 150kg
Note that volume = length x breadth x height 
Volume = 20 x 10 x 5 
Volume = 1000m³
Density = mass ➗ volume 
Density = 150kg ➗ 1000m³
Density = 0.15kg/m³

At the most distant point, the size of the speed is zero (0 m/s). This is a direct result of preservation of vitality. PE = KE. The most distant far from the harmony position is the maximum PE. Hence it can have no KE. No KE implies no speed since KE = .5mv2
