Question:
A diver of mass kg takes off from the m platform from a standing position by jumping upwards with a near vertical speed of ms
a Calculate
i the time taken to reach the water;
ii the initial gravitational potential energy;
iii the initial kinetic energy.
b Use methods uniform motion equations and the principle of conservation of energy to check the accuracy of the statement at the beginning of the passage that a diver jumping from the high platform will hit the water at mph
c Sketch graphs of i displacement against time and ii velocity against time for the dive, pointing out the important features of the graphs and the relationship between the two graphs.
