Calculate the impulse exerted when a 1-kg object falls on your foot if the contact time is 0.1 sec. (Hint: first find the weight of the object)

Respuesta :

AL2006
The weight of an object is

         (its mass) x (acceleration of gravity).

The weight of a 1 kg object on Earth is  (1 kg) x (9.8 m/s²) = 9.8 newtons.

When a force of 9.8 newtons acts for 0.1 second,
the impulse imparted to the unfortunate toe is 

                   0.98 newton-second = 0.98 kg-m/s
