Answer:
60m/s
Explanation:
initial energy = final energy
g.p.e = k.e
k.e = 0.5 × mass × velocity²
g.p.e = 990000J as per Question
990000Nm = 0.5 × 550 × V²
V² = 3600
V = 60m/s
Answer: TV announcers intend to mean “change of speed” or “velocity” when they talk about “high rate of change”. According to physics, they mean “acceleration”.
