A car falls off a ledge and drops to the ground in \(0.5\ s\). Let \(g\ =\ 10\ ms^{–2}\) (for simplifying the calculations).
(i) What is its speed on striking the ground?
(ii) What is its average speed during the \(0.5\ s\)?
(iii) How high is the ledge from the ground?
(i) What is its speed on striking the ground?
(ii) What is its average speed during the \(0.5\ s\)?
(iii) How high is the ledge from the ground?
Speed \(=\) \(ms^{-1}\)
Average speed \(=\) \(ms^{-1}\)
Height of the ledge from the ground \(=\) \(m\)
(Note: Enter your answer with two decimal digits)
