Results for computing crater size from projectile diameter Your Inputs: Projectile Descriptors Projectile Diameter 0.10 meters Projectile Density 1000 kg/m3 Impact Conditions Impact Velocity 17 km/sec Impact Angle 45 degrees Target Descriptors Target Density 1000 kg/m3 Acceleration of Gravity 9.8 m/sec2 Target Type competent rock or saturated soil Results The three scaling laws yield the following transient crater diameters (note that diameters are measured at the pre-impact surface. Rim-to-rim diameters are about 1.25 times larger!) Yield Scaling 2.59 meters Pi Scaling (Preferred method!) 7.55 meters Gault Scaling 3.21 meters Crater Formation Time 5.16 x 10-1 seconds Using the Pi-scaled transient crater, the final crater is a Simple crater with a rim-to-rim diameter of 1.18 x 101 meters. This impactor would strike the target with an energy of 7.57 x 107 Joules (1.81 x 10-8 MegaTons).
Initially, there were reports of an explosion in Kangundo, Tala, Yatta and Kakuzi before an extra-terrestrial rock fell at around 10 am. Area residents say the loud sound was comparable to a bomb explosion or a crashing aircraft while others felt it was an earthquake. Police and military officers from Thika rushed to the scene at Kiumwiri village, Murang’a county. The military later took away the object for expert analysis. The black smooth rock weighing about five kilos fell at a maize plantation, 60 meters from a nearby homestead, but no one was harmed.

That may be the case..but allowing for the reduction in speed, the eye witnesses talk of a shaking and a loud explosion..surely that has to account for something
Eyewitnesses stated that the object was spinning on impact when it landed in a cornfield. Police and military officers quickly responded to the scene and found an extremely hot object, weighing in at approximately 11 pounds. They eventually took the object for expert analysis.
