The rare NASA photo above demonstrates cows are in fact able to jump over the
The energy required to launch an object from the Earth is given by the following
- How much energy must a 450 kg cow expend in jumping over the moon?
(Don't worry about the moon's gravity or the Earth's atmosphere...)
- Assuming all the work is done during the jump itself, what would
her initial velocity have to be?
- What would her final velocity be upon her return to Earth?
- Again assuming all the work would be done during the initial jump, i.e.
for a distance approximately the length of her legs (1 meter), what would her
acceleration need to be?
