(b) Explain any THREE causes of environmental degradation (c) A stone of mass 10kg is thrown to a height of 100m.
i. What is the kinetic energy (K. E) at the maximum height?
ii. What is the potential energy (P. E) at the maximum height?
111.
What is the K. E and P. E just as the stone strikes the ground?
iv. Calculate the K. E and hence the velocity after falling 50m (take g=10ms).
