A chicken’s egg of mass 58 g is dropped onto grass from a height of 1.1 m. Assume that air resistance is negligible and that the egg does not bounce or break.

Show that the kinetic energy of the egg just before impact is about 0.6 J.

Markscheme

Ek = mgh =  0.058 × 9.81 ×1.1 = 0.63 J ✔

Allow use of g = 10 m s−2 (which gives 0.64 «J»)

Substitution and at least 2 SF must be shown
