Cat cuddling forces!

Classical Mechanics Level 1

How much force should it take to hold a 7 7 kilogram cat? Assume we are at an area where the influence of gravity is 9807 1000 \frac{9807}{1000} meters per second squared.

7 7 Newtons 16807 1000 \frac{16807}{1000} Newtons 68649 1000 \frac{68649}{1000} kilograms 68649 1000 \frac{68649}{1000} Newtons

Remember that for force of gravity F F , mass m m and influence of gravity (aka gravitational field) a a , F = m a F = ma . Therefore, F = 7 ∗ 9807 1000 F = 7 * \frac{9807}{1000} or F = 68649 1000 F = \frac{68649}{1000} . Of course, watch out for your units! When you multiply kilograms by meters per second, you get Newtons, so the answer is not 68649 1000 \frac{68649}{1000} kilograms.
