Answer:
Explanation:
easy way
when system is all kinetic energy, velocity is at a maximum
E = ½mv²
v = √(2E/m) = √(2(25)/0.5) = √100 = 10 m/s
harder way
ω = √(k/m) = √(80/0.5) = √160 rad/s
When the system is entirely spring potential, the amplitude A is
E = ½kA²
A = √(2E/k) = √(2(25)/80) = 0.790569... = 0.79 m
maximum velocity is ωΑ = 0.79√160 = 10 m/s

Answer:
Thus, the maximum height is 7.35 m.
Explanation:
initial velocity, u = 12 m/s
acceleration due to gravity, g = 9.8 m/s^2
Velocity at maximum height, v = 0 m/s
Let the maximum height is h.
Use third equation of motion
