Using the formulae, S= ut + ½ at2 ; K.E= ½ mv2 and P.E=mgh, compute the time it takes for a 1tonne vehicle dropped at a height of 1 mile above the ground will take before landing at point B on the ground. Compute the minimum speed that a 5 meter long vehicle located at point A and 1 mile away from point B will need to safely drive past point B before the falling vehicle lands. Use g= 9.8m/s2 and 1 mile= 1.6km
